Given the depth vs. clock time function y = f(t) = .019 t² + -2.49 t + 96, with depth in cm when clock time is in seconds, find the clock time when water depth is 70.41974 cm. Using the same function determine the depth at clock time t = 13 sec. Find t such that f(t) = 39.41974. Find f(t) when t = 32.
