Population growth in the U. S. between 1950 and 2000, in millions, can be represented by the function \large f\left(t\right)=150e^{\left(0.013t\ right)} where t is the number of years since 1950. In part b of question 1, you found the point of intersection between y = f(t) and y = 200. Describe what it means in this situation.
