To find the coordinate of the vertex, set the inside of the absolute value equal to . In this case, .
Replace the variable with in the expression.
The absolute value is the distance between a number and zero. The distance between and is .
The absolute value vertex is .
The domain is the set of all valid values. Use the graph to find the domain.
For each value, there is one positive value and one negative value. Select few values from the domain. It would be more useful to select the values so that they are around the value of the absolute value vertex.
