Question

Which two functions are inverses of each other​

Answer 1

f(x) = 4x, g(x) =
`(1)/(4)x`

Explanation:

Inverse function is when you switch the x and the y and solve for x

f(x) = 4x

y = 4x

x = 4y

Now solve for x

y =
`(1)/(4)x`

g(x) =
`(1)/(4)x`

If you try that with the other functions, none of them work.

Answer 2

C. f(x)= 4x, g(x)= 1/4x

Explanation:

inverse functions are flipping x and y corrdinates so let's plug in x=1 into f(x) and get y = 4

now plug in x = 4 into g(x) and check if the answer is 1 - yes ,it is!
