Khan Academy: Graph Absolute Value Functions

What is absolute value? What is an absolute value function? Emerging mathematicians solve equations containing variables inside an absolute value sign.  They graph each function on a coordinate plane and identify the maximum and...

Can you solve an equation graphically? Absolutely! This Algebra II lesson makes the connection between solving an absolute value equation and graphing two functions. Graphing absolute value functions is presented through the process of...

One of the strongest tools an algebra learner develops is the ability to quickly and accurately graph almost any given function. Often doing this quickly and accurately requires rigid transformations to a parent function,...

Sal reviews absolute value equations by taking viewers through a careful and deliberate problem-solving process. Those who didn't thoroughly understand absolute value during class will appreciate Sal's steady and straightforward...
