Question

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

Oh(x) = x + 4
Oh(x) = x - 4
h(x) = x
Oh(x) = = x

Answer 1

y = x/4

Explanation:

First, replace f(x) with y, so it's easier to find the inverse:

y = 4x

To find the inverse of this function, you would replace all the y's with x's and all the x's with y's, and then solve for y. That would be:

x = 4y

y = x/4

Therefore, the inverse function of y = 4x is y = x/4.
