If f(x) = 3x + 2, find f(f–1(14))

Question

this is an algebra 2 word problem 

Answer 1

Assuming you want f(f^-1(14)):

A function and its inverse (if one-to-one) have the property of "undoing each other."

If f(x) = y, the f^-1(y) = x.

f(f^-1)(y) = y!

f(f^-1)(14) =14

Answer 2

It looks like the second f is missing parenthesis or they are in the wrong place.
