See the entire solution process below:

#### Explanation:

To solve this we must substitute $\textcolor{red}{2}$ for every occurrence of $\textcolor{red}{x}$ in the function:

$w \left(\textcolor{red}{x}\right) = 4 \textcolor{red}{x} - 1$ becomes:

$w \left(\textcolor{red}{2}\right) = \left(4 \times \textcolor{red}{2}\right) - 1$

$w \left(\textcolor{red}{2}\right) = 8 - 1$

$w \left(\textcolor{red}{2}\right) = 7$
