Question

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

® h(x) = x + 4
O h(x) = x- 4
H(x) = =x
O h(x) = ÷x

Answer 1

`\displaystyle h(x) = (1)/(4)x`

Explanation:

Sinse in this case you are dealing with direct variation, all you are doing is taking the multiplicative inverse of 4, which is ¼:

`\displaystyle f(x) = 4x \rightarrow f^(-1)(x) = (1)/(4)x`

This option is not an answer choise. Perhaps there was a typographical errour.
