Question

Given the function f(x) = 4(x+3) − 5, solve for the inverse function when x = 3.

Answer 1

let f(x) = y
y = 4(x + 3) - 5
y = 4x + 12 - 5
y = 4x + 7

now can you solve this for x?

Answer 2

I just put the value of x in place of the x, correct?

Answer 3

So that would be 4(3) + 7 = 19, yes?

Answer 4

But I am supposed to find the inverse function @welshfella
