Question

How do you find the average rate of change of a function between two points?

Answer 1

Average change= change in `y` divided by change in `x`

Explanation:

Let's say we have points `(x_1,y_1)and (x_2,y_2)`

Then average change=`(Deltay)/(Deltax)=(y_2-y_1)/(x_2-x_1)`

When we're talking about average change, the form of the graph is totally unimportant. Just the beginning and end point count.
