What does an inverse function do to the inputs and outputs of the original?
AIt doubles them both
BIt squares them both
CIt leaves them alone
DIt swaps them over
Answer & Solution
Correct answer: D. It swaps them over
1. An inverse function runs the original machine backwards.
2. The input of the original function becomes the output of the inverse.
3. The output of the original function becomes the input of the inverse, so the two swap over.
