| Summary: | This lesson begins with the definition of absolute value and then introduces the absolute value function. Graphs are shown of the absolute value of a linear function as well as the absolute value of a quadratic function. Linear equations are solved algebraically and graphically.
After this lesson, you will be able to:
- understand the definition of absolute value.
- draw the graph of the absolute value of a linear function
- draw the graph of the absolute value of a quadratic function
- solve linear absolute value equations with one absolute value symbol algebraically and by graphing
- solve linear absolute value equations with two absolute value symbols and a constant of zero algebraically and by graphing
- understand critical numbers and intervals.
- solve linear absolute value equations with two absolute value symbols and a non zero constant algebraically and by graphing
