# Given f(x) = 3|x + 5| + 8, what is the vertex of the graph of f(x)?

Jun 16, 2017

#### Answer:

Vertex: $\left(x , y\right) = \left(- 5 , 8\right)$

#### Explanation:

$f \left(x\right)$ is linear in except at the point where $\left\mid x + 5 \right\mid = 0$

At $x = 0$,
$\textcolor{w h i t e}{\text{XXX}} y = f \left(0\right) = 8$
