Question

Which represents the inverse of the function f(x) = 4x?

Answer 1

Answer: D

Step-by-step explanation:

To find the inverse, you switch x with y and y with x. Then, you solve for y.

y=4x         [switch y with x and x with y]

x=4y         [divide both sides by 4]

y=x/4

Now, we know the answer is D.
