Question

what is the inverse function for f (x)=5x-3/8

Answer 1

f(x) = y... to find the inverse you need to switch x and y and then solve for y. when you do, y will be f inverse.

Answer 2

so for your problem, y = 5x - 3/8

switch x and y so you get:

x = 5y - 3/8

now, solve for y and that will be f inverse.
