Question

How do you find the rate of change of a function?​

Answer 1

Answer:

We calculate the slop of a line.

How to find the slope:

Pick any two points on a graph

The formula of slope is $\frac{Y2-Y1}{X2-X1}$

For example we have two points that contains the coordinates (5,2) (7,4)

Inserting them to the formula would result in:

$\frac{4-2}{7-5}$

=$\frac{2}{2}$

Our rate of change is rise 2, run 2.
