Sketching Absolute Value Functions - Conceptual Approach

In this short video I show how to sketch absolute value functions. The absolute value function takes negative input values and makes them positive. On a graph, we would take the negative parts under the x-axis and reflect them over the x-axis.
I show how to sketch absolute value linear, absolute value quadratic and absolute value trig functions. This technique is very useful for students in precalculus and calculus.

Quick and straight to the point thank you

Glad you think so! The reflection concept is subtle but very useful for precalc and calc.
