I have to record myself answering questions for my math class and I really need help. I will reward 36 points. How can you tell if 2 functions are inverses of each other?

If the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions. But, we need a way to check without the graphs, because we won't always know what the graphs look like! then f(x) and g(x) are inverse functions.

Step-by-step explanation: Hope this helps :)

the answer is  

d.

121π mi^2

hope you got it chief
