steps to find the inverse of a function

step 1: replace f(x) with y

step 2: replace all x's with y's and y's with x's

step 3: solve for y

step 4: replace y with , the ineverse of f(x) or whatever function name

given

step 1: replace f(x) with y

step 2: replace all x's with y's and y's with x's

step 3: solve for y

step 4: replace y with function name

here's where we just match which one matches

that would be A
