$y = | x + 2 |$

Step 1

To find the $x$ coordinate of the vertex, set the inside of the absolute value $x + 2$ equal to $0$ . In this case, $x + 2 = 0$ .

$x + 2 = 0$

Step 2

Subtract $2$ from both sides of the equation.

$x = - 2$

Step 3

Replace the variable $x$ with $- 2$ in the expression.

$y = | (- 2) + 2 |$

Step 4

Simplify $| (- 2) + 2 |$ .

Step 4.1

Add $- 2$ and $2$ .

$y = | 0 |$

Step 4.2

The absolute value is the distance between a number and zero. The distance between $0$ and $0$ is $0$ .

$y = 0$

Step 5

The absolute value vertex is $(- 2, 0)$ .

$(- 2, 0)$
