4. A function consists of the pairs (2,3), (x, y) and (5,6). If the inverse is also a function what values can y NOT be? Explain.

In a nutshell, cannot be 3 or 6 in the inverse function for all distinct from 2 and 5.

Step-by-step explanation:

From Functional Theory we remember that a function is a relation in which all elements of its domain has an unique and different element from range. If is the image of the inverse, which is a function, then . Otherwise, the inverse could not be a function when .

In a nutshell, cannot be 3 or 6 in the inverse function for all distinct from 2 and 5.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
