** WILL FAN & MEDAL **
Which pair of functions is not a pair of inverse functions?

A) f(x) = x+1/6 and g(x) = 6x-1

B) f(x) = x-4/19 and g(x) = 19x+4

C) f(x) = x^5 and g(x) = ^5sqrtofx

D) f(x) = x/x+20 and g(x) = 20x/x-1

Answer 1

to find inverse function complete the folowing steps:

Replace every x with a y and replace every y with an x.
Solve the equation.

Answer 2

do this for every function and check which will not be inverses.

Answer 3
