Traffic flow measures the number of cars that pass through an intersection per minute. It can be modeled by the function f(t) = 10 + 8 cos() for 0 ≤ t ≤ 15 where f(t) is measured in cars per minute and t is measured in minutes. Is the traffic flow increasing or decreasing at t = 10? Give a reason for your answer.
