A rock is thrown upward from a bridge that is 21 feet above a road. The rock reaches its maximum height above the road 0.62 seconds after it is thrown and contacts the road 3.51 seconds after it was thrown. Write a function f that determines the rock's height above the road (in feet) in terms of the number of seconds t since the rock was thrown. f(t) = Preview Hint: the function f can be written in the form f(t) = c · (t – t1)(t – t2) for fixed umbers c, t1, and t2.
