Question

Steps for finding the inverse of f(x)=4x-7?

Answer 1

the same as every other inverse problem. replace f(x) with y.
exchange the y and x variables. solve for y

Answer 2

I understand that, but I'm confused what to do after I get x+7 over 4.

Answer 3

y=4x-7
x=4y-7
x+7=4y
\(\huge \frac{x+7}{4}=y\)

you got it

Answer 4

Oh alright, thanks :)
