Question: WORLD POPULATION The total world population is forecast to be
P(t) = 0.00074t3 - 0.0704t2 + 0.89t + 6.04 (0 ≤ t ≤ 10)
In year t, where t is measured in decades with t = 0 corresponding to 2000 and P(t) is measured in billions.
a. Show that the world population is forecast to peak around 2071. Hint: Use the quadratic formula.
b. What will the population peak at?
