After you eat something with sugar, the pH or acid level in your mouth changes. This can be modeled by the
L(m) =
-20m + 7
m² +4
where L is the pH level and m is the number of minutes that have elapsed since eating.
a) Find the average rate of change of pH level with respect to
time over the time interval me[2, 4] by using the equation.
b) Estimate the instantaneous rate of change at 1 minute
(m1) by using the graph.
