Problem
Amir throws a stone off of a bridge into a river. The stone's height (in meters above the water) seconds after Amir throws it is modeled by
Amir wants to know when the stone will reach its highest point.
1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation.
2) How many seconds after being thrown did the stone reach its highest point?
