Question

Please help Select the correct answer. Find the inverse of function f. F(x) = 9x-7

Answer 1

f-1(x)=(x+7)/9

Explanation:

Try going at the problem backwards. The function first multiplies x by 9 then subtracts 7, so the opposite route for the inverse. Add 7 to x and then divide everything by 9
