Average rates of change is the change in the quantity of the dependent variable divided by the corresponding independent variable over an intervals.

Graphically, the average rate of change over an interval is equivalent to the
slope of the secant line passing through two points.

Average rate of change= ChangeinDistancingUnit/ChangeinTime

AVG= Y axis values (dependent valuess) DIVIDED BY X axis values (independent values)

Quartics and Cubic Functions for dummies :P

In which this guy emphasizes and compares the turning points, max, min points, end behaviors, etc of cubic and quartic polynomial functions.

I was actually in love with this song waaay before it got viral. Good song to jam to while doing functions.
