Question

Inverse Functions (please help)

Answer 1

The procedure for this case is add three, then divide by 5.

Explanation:

if y=5x-3

to find the inverse, we exchange x and y then solve for the new y.

x=5y-3 add 3

x+3 = 5y divide by 5

(x+3)/5 = y

or

inverse, y=(x+3)/5

The procedure for this case is add three, then divide by 5.
