I am doing a self-study and review of calculus 1 material.
I came across this question.
Given p(t) = 500[1 + (4t/(50+t^2)]
Note that t is measured in hours.
Find the rate at which the population is growing
when t = 2.
Must I find the derivative of p(t) before replacing t with 2 or just plug t = 2 into the given formula?
