$f \left(- 5\right) = 2 + \sqrt{- 3 \left(- 5\right) + 1} = 2 + \sqrt{16} = 6$

#### Explanation:

The only relevant function definition among those included in the question is
$\textcolor{w h i t e}{\text{XXXX}}$$f \left(x\right) = 2 + \sqrt{- 3 x + 1}$

To evaluate $f \left(- 5\right)$
simply replace the $x$ in the function definition with $\left(- 5\right)$ as shown and perform the arithmetic operations.
