Question

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

Oh(x)=x+4
Oh(x)=x-4
Oh(x) = 3/4x
○ h(x) = 1/4x

Answer 1

(d) h(x) = 1/4x

Explanation:

You want to know the inverse of the function f(x) = 4x.

Inverse function

The inverse of y = f(x) will be the solution to x = f(y).

x = f(y)

x = 4y . . . . . . substitute the argument in the function definition

x/4 = y . . . . . divide by 4 to solve for y

The inverse function is ...

h(x) = (1/4)x
