Answer:
-1
f (x) = x/2 - 3/2
Step-by-step explanation:
I choose to address this question by actually finding the inverse of f(x) = 2x + 3.
1) replace f(x) with y: y = 2x + 3
2) interchange x and y: x = 2y + 3
3) solve this result for y: 2y = x - 3 , or y = (x - 3)/2. This is the same as the second answer choice. Label this result as
-1
f (x) = x/2 - 3/2
