Question

8. After you eat something containing sugar, the pH or acid level in your mouth changes. This can be modelled by the function below, where L is the pH level and n is the number of minutes that have elapsed since eating.
L(n)= 6- 20.4n/(n^2 +36)

Estimate the instantaneous rate of change at 3 minutes. Explain what the value represents in this situation.

Could someone please help me with this and especially the explanation part.
