Question: MARIJUANA ARRESTS The number of arrests for marijuana sales and possession in New York City grew at the rate of approximately

f(t) = 0.0125t⁴ - 0.01389t³ + 0.55417t² + 0.53294t + 4.95238    (0 ≤ t ≤ 5)

Thousand/year, where t is measured in years, with t = 0 corresponding to the beginning of 1992. Find the approximate number of marijuana arrests in the city from the beginning of 1992 to the end of 1997.
