Determine the average rate at which the quadratic function y = .015 t² + -1.9 t + 93 changes between clock times t = 33.4 and t = 33.4 + .1 sec; between clock times t = 33.4 and t = 33.4 + .01 sec; and between clock times t = 33.4 and t = 33.4 + .001 sec. At what rate do you conjecture this function will be changing at the instant t = 33.4 sec?
