A snowball is thrown upward from a bridge into a river below. The function f(t): above the surface of the water (in feet) in terms of the number of seconds t since the snowball was thrown. 16t+ 47t + 88 determines the height of the snowball To help you answer questions c. and d., remember that a parabola is symmetric about the vertical line through the vertex (axis of symmeiry) and so both zeros of f are the same distance from the axis of symmetry. Depict the path off the snowball by hand (do not use an external tool/grapher). a. What is the bridge's height above the water? feet Preview b. How many seconds after being thrown does the snowball hit the water? seconds Preview c.
