Use compositions to determine if the functions below are inverses of each other?*
f(x) = 5x & F-1(x) = x
Yes
No

They are not inverse functions

Step-by-step explanation:

Given

Required

Determine if both are inverse functions

First calculate the inverse of f(x)

Replace f(x) with y

Swap x and y

Make y the subject

Replace y with f-1(x)

By comparison:

and are not the same:

Hence:

and are not inverse functions
