See a solution process below:

#### Explanation:

For each occurrence of $\textcolor{red}{x}$ in the function substitute $\textcolor{red}{4}$ and calculate the result:

$f \left(\textcolor{red}{x}\right) = \textcolor{red}{x} - 11$ becomes:

$f \left(\textcolor{red}{4}\right) = \textcolor{red}{4} - 11$

$f \left(\textcolor{red}{4}\right) = - 7$
