A rock is thrown upward from a bridge into a river below. The function f(t) = -16t² + 37t + 116 determines the height of the rock above the surface of the water (in feet) in terms of the number of seconds t since the rocket was thrown. **Must show ALL algebraic work to receive full credit.** a. What is the bridge's height above the water? b. How many seconds after being thrown does the rock hit the water?
