Question

Which function is the inverse of f(x) = 8x + 4?A. 5-18) = —841 – 4)B. 7-14x) = 554OC. 5-11%) = 8.1 – 4)OD. 1x) = -1

Answer 1

`f^(-1)(x)=(x-4)/(8)`

Explanation:

We have the following function:

`f(x)=8x+4`

We calculate the inverse function as follows:

`\begin{gathered} x=8\cdot f^(-1)(x)+4 \\ 8\cdot f^(-1)(x)=x-4 \\ f^(-1)(x)=(x-4)/(8) \end{gathered}`
