The function, q(t), represents the population of a whale species on the interval 0 < t < 20, where t represents the years after 1990. (t = 0 in 1990) q(t) = 23e0.03t describe the behavior of the function on the interval (0, 20). a. the function, q(t), increases on the interval (0, 20). b. the function, q(t), decreases on the interval (0, 20). c. the function, q(t), increases on the interval (0, 10) and decreases on the interval (10, 20). d. the function, q(t), decreases on the interval (0, 10) and increases on the interval (10, 20).
