Enter a problem... Algebra Examples Popular Problems Algebra Graph g(x)=|x| Step 1Find the absolute value vertex. In this case, the vertex for is .Tap for more steps...Step 1.1To find the coordinate of the vertex, set the inside of the absolute value equal to . In this case, .Step 1.2Replace the variable with in the expression.Step 1.3The absolute value is the distance between a number and zero. The distance between and is .Step 1.4The absolute value vertex is .Step 2The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.Interval Notation:Set-Builder Notation:Step 3For each value, there is one value. Select a 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.Tap for more steps...Step 3.1Substitute the value into .
