(a) A function that is neither one-to-one nor onto is, f(x) = 1 for all x ∈ Z (the set of all integers).

(b) A function that is one-to-one but not onto is, f(x) = |x| for all x ∈ Z.

(c) A function that is onto but not one-to-one is, for example, f(x) = ⌈x/2⌉ for all x ∈ Z.

(d) A function that is one-to-one and onto is, for example, f(x) = x + 1 for all x ∈ Z.

(a) A function that is neither one-to-one nor onto is, for example, f(x) = 1 for all x ∈ Z (the set of all integers). This function maps every integer to the positive integer 1, so it is not one-to-one, since multiple inputs are mapped to the same output, and it is not onto, since not every positive integer is in the range of the function.

(b) A function that is one-to-one but not onto is, for example, f(x) = |x| for all x ∈ Z. This function maps every integer to its absolute value, which is always a positive integer. The function is one-to-one because each input has a unique output, but it is not onto because there is no positive integer that is not the absolute value of some integer.

(c) A function that is onto but not one-to-one is, for example, f(x) = ⌈x/2⌉ for all x ∈ Z. This function maps every integer to the smallest integer greater than or equal to x/2. Since every positive integer is the ceiling of some integer, the function is onto. However, it is not one-to-one, because both x and x+1 are mapped to the same output when x is odd.

(d) A function that is one-to-one and onto is, for example, f(x) = x + 1 for all x ∈ Z. This function maps every integer to a unique positive integer (namely, x+1), and every positive integer is the image of some integer under this function. Therefore, it is both one-to-one and onto.

Step-by-step explanation:

When 'a' is 10, 'c' is approximately 142.97. You can repeat this process for different values of 'a' to find corresponding values of 'c'. Keep in mind that there are infinitely many solutions to this equation

To use the elimination method to solve the equation 2a + c = 162.97, we need another equation with the same variables. However, as there is only one equation given, we cannot apply the elimination method directly.

The elimination method typically involves adding or subtracting equations to eliminate one of the variables, resulting in a new equation with only one variable. Since we have only one equation, we don't have the opportunity to eliminate variables using another equation.

In this case, we can solve the given equation directly by isolating one variable in terms of the other. Let's solve for 'c':

2a + c = 162.97

Rearrange the equation to isolate 'c':

c = 162.97 - 2a

Now, we have an expression for 'c' in terms of 'a'. This equation represents a line in the 'a-c' coordinate plane. We can choose any value for 'a', substitute it into the equation, and calculate the corresponding 'c' value.

For example, let's say we choose 'a' = 10:

c = 162.97 - 2(10)

c = 162.97 - 20

c = 142.97

So, when 'a' is 10, 'c' is approximately 142.97.

You can repeat this process for different values of 'a' to find corresponding values of 'c'. Keep in mind that there are infinitely many solutions to this equation since we have one equation and two variables.

Slope of the line having passing points (6,-5) and (-6,-5) is 0.

What do you mean by slope of the line?

A line's slope is defined as the ratio of the change in y coordinate to the change in x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

Hence, the change in y-coordinate with regard to the change in x-coordinate is given by,

m =  change in y/change in x

Given passing points :

(6,-5) and (-6,-5)

Slope of the line having passing points (x,y) and (a,b) is given by \(\frac{b-y}{a-x}\)

Answer:

When multiplying, add the exponents, (example) remember if there is "7b" the exponent is one.

Multiply b^2 * b^3 = b^5  (add the exponent 2 + 3 = 5)

Multiply 7b * b^3 = 7b^4 (the exponent of 7b is one, add 1 + 3 for the exponent to become 4)

Multiply 4 * b^3 = 4b^3 (4 doesn't have a variable, the exponent will be 3)

b^2 * b*2 = b^4 (add exponents)

7b * b^2 = 7b^3 (add the exponents 1 + 2)

4 * b^2 = 4b^2

              b^2             +               7b             +        4

In a nutshell, \(f(x)\) is obtained by applying an horizontal translation on \(g(x)\), followed by a vertical translation.

Step-by-step explanation:

Let be \(g(x) = x^{3}\) the parent function, \(f(x)\) is obtained by applying an horizontal translation on \(g(x)\), followed by a vertical translation, that is:

\(f(x) = g(x-a)-b,\,a,b\in\mathbb{R}\) (1)

If \(a > 0\), then translation is rightwards.

If \(b > 0\), then translation in downwars.

If \(a = 2\) and \(b = 1\), then the resulting function is:

\(f(x) = g(x-2)-1\)

\(f(x) = (x-2)^{3}-1\) (2)

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.

The correct answer is 4.

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.

Given information:

- Circle C (cats): 15

- Circle D (dogs): 21

- Circle F (fish): 12

- Overlap of C and F: 2

- Overlap of F and D: 0

- Overlap of D and C: 3

- Overlap of all 3 circles: 1

- Number outside of circles: 14

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.

From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.

To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.

Therefore, from the options given correct one is 4.

Based on the diagram, we can see that the triangle formed by the line segment with length 8 and the two dashed line segments is a right triangle with a 45° angle. This means that the other two angles of the triangle are also 45° each.

Using the properties of 45°-45°-90° triangles, we know that the length of the hypotenuse is equal to the length of either leg times the square root of 2. Therefore, we have:

x = 8 / sqrt(2) = 8 * sqrt(2) / 2 = 4 * sqrt(2)

So the value of x is option B: 8√2 / 2 or simplified, 4√2.

The reasoning presented lacks explicit explanations and logical connections between the steps, making it difficult to fully understand the intended proof strategy.

The given proof aims to show that the Separation Axioms can be derived from the Replacement Schema using a particular construction involving a formula p(x, y). Let's analyze the proof step by step:

Define the formula p(x, y) as x = yo(x).

This formula states that for each x, y pair, x is equal to the unique object y such that y is obtained by applying the operation o to x.

Define the set F as {(x, x) (x)}.

This set F contains pairs (x, x) where x is the unique object obtained by applying the operation (x) to x.

Claim: F(X) = {y (x = X)p(x, y)} = {y: (x = X)x = y^o(x)} = {x: (3x € X)o(x)} = {x X: (x)}.

This claim asserts that F(X) is equivalent to {y (x = X)p(x, y)}, which is further equivalent to {y: (x = X)x = y^o(x)}, and so on.

The proof states that since (x, y) satisfies the functional formula VaVyVz(p(x, y)^(x, z) y = z), it follows that (x, y) is a functional formula.This step emphasizes that the formula p(x, y) satisfies certain properties that make it a functional formula, which is relevant for the subsequent deductions.

Finally, the proof concludes that the Separation Axioms follow from the Replacement Schema, based on the previous steps.
