Answer:
1.5 - it represents the time in seconds where the ball is highest
Step-by-step explanation:
There are 2 methods of approaching this.
The first method involves graphing, simply place into a graphing calculator and view the vertex. The horizontal line coming down from the vertex is the axis of symmetry (it splits the parabola in half).
The second method is finding the axis of symmetry (vertex) algebraically.
-b/2a is the equation used to find the x term of the vertex, and if we were to substitute our values in, we'd get -48/-32, giving us 1.5
