What function is the inverse of f (x) = 2x + 3?

Step-by-step explanation:

f (x) = 2x + 3 ... change f (x) to y

y = 2x + 3 ... switch the x and y and solve for y

x = 2y + 3

(x - 3) = 2y

(x - 3) / 2 = y or y = 1/2x - 3/2 <===

can be written as : f-1 (x) = (x - 3) / 2 ... f-1 (x) is the inverse

Inverse just means back wards pretty sure
