Question

What is the inverse of the function below?

Answer 1

Answer:

Option B is the correct answer.

Step-by-step explanation:

$\texttt{We have }f(x)=y=\frac{2x+12}{5}$

Finding inverse,

          $y=\frac{2x+12}{5}\\\\5y=2x+12\\\\2x=5y-12\\\\x=\frac{5y-12}{2}\\\\f^{-1}(x)=\frac{5x-12}{2}=\frac{5}{2}x-6$

Option B is the correct answer.
