Question

The function f is one-to-one. Find its inverse.

Answer 1

the most simple way to find the solution to this problem is to find x in terms of y and swap them to get your fnction

Answer 2

so we have
waht hero did already so we r done :)

Answer 3

y = f(x), therefore:

y = (8x+3)/5

5y = 8x+3
5y-3 = 8x
(5y-3)/8 = x
(5x-3)/8 = y
f^-(x) = (5x-3)/8

Answer 4

Made a slight mistake, but corrected it
