# What are the coordinates of the vertex of the graph of y= |x+2|-4?

Dec 5, 2016

The vertex is $\left(- 2 , - 4\right)$.

#### Explanation:

The equation for an absolute value function is

$y = \left\mid x - h \right\mid + k$ where $\left(h , k\right)$ is the vertex.

Compare that equation to the example.

$y = \left\mid x + 2 \right\mid - 4$

The vertex is $\left(- 2 , - 4\right)$.

Note that you have to change the sign of the number $h$ inside the absolute value symbol because $h$ is subtracted.
