Which represents the inverse of the function f(x) = 4x?
zhenek [66]

Answer:

h(x) = 1/4x

Step-by-step explanation:

To find the inverse, first we rewrite the function using y instead of f(x):

y = 4x

Next we switch x and y:

x = 4y

Solve for y by dividing both sides by 4:

x/4 = 4y/4

x/4 = y

1/4x = y
