Question

Determine if the inverse of function {(-3, -6), (-1, 2), (1, 2), (3, 6)} is also a function.

A. function
B. not a function

Answer 1

To find the inverse, swap the x and y values.
You get:
{(-6,-3), (2,-1), (2,1) (6,3)}
You want to see if there are any duplicate x-values; a duplicate means there is an inverse.
