Determine whether the function is invertible. If it is, find the inverse.
-{(-9, 6), (-8, 6), (-7, 6), (-6, 4)}
A) {(-9, 4), (-9, 6), (-7, -8)}
B) {(6, -9), (-8, 6), (-7, 4)}
C) {(6, -9), (4, 6), (-7, -8)}
D) Not invertible

Question

Quizplus · Accepted Answer

For a function to be invertible, each input must map to a unique output. This function maps different inputs (-9, -8, -7) to the same output (6), making it not invertible.
