Net Change and Average Rate of Change (2.4: 2, 3, 5, & 6)

These two are from class: #3 & #6.


This is another #6 with requested red numbers and #5.

This is #2. The problem has a graph that looks like a piece of a cubic function with two points marked. The only part that matters is the two points. The net change is the difference in the y-values. The average rate of change is the difference in the y-values divided by the difference in the x-values, just like the slope of a line. Remember that both are signed values: moving from lesser x to greater.
