Question

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

Answer 1

Finding the inverse of the function f(x) = 4x

Re-write it as:

y = 4x

Put x in place of y and y in place of x

x = 4y

Write the expression by making y the subject

y = x/4

The inverse of the function f(x) is h(x) = 4/x

None of the given functions is the inverse of f(x) = 4

Answer 2

Thank you for asking this question.

here is your answer:

Finding the inverse of the function f(x) = 4x

y = 4x

Put x in place of y and y in place of x

x = 4y

Here we will make y the subject:

y = x/4

The inverse of the function f(x) is h(x) = 4/x

None of the given functions is the inverse of f(x) = 4
