SOLUTION: Consider f(x) = 2x + 3. Find the inverse of this function. Verbally, compare what f does to x (“multiply by 2, then add 3”) to what f-1 does to x.

Question 1135319: Consider f(x) = 2x + 3. Find the inverse of this function. Verbally, compare what f does to x (“multiply by 2, then add 3”) to what f-1 does to x. Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! y = 2x + 3
:
solve for x
:
2x = (y - 3)
:
x = (y - 3)/2
:
interchange x's and y's
:
y = (x - 3)/2
:
*********************************************************
f^(-1) (x) = (x - 3)/2
:
f inverse subtracts 3 from x and divides the result by 2
