Videos are available in ALEKS (www.aleks.com) for each section of material that we cover. You may access them in the etext or the homework problems.
Additional videos for each section are also listed below:
Applications of Linear Equations
Applications of Quadratic Equations
Other Types of Equations (We do not cover the radical equations.)
Absolute Value Equations (We do not cover the absolute value inequalities.)
3.3 & 3.4 Piecewise Functions and Graphing Functions (The directions for the last example on this video should ask for a reflection across the x-axis, not the y-axis.)
