Answer:
It hit the ground at t=2
It reaches its highest point at t=1
Its maximum height =16
Step-by-step explanation:
The graph of the function of the height will be a parapola opening downward where it's x intercepts = the time where the object hit the ground and its maximum point = the point with the maximum point
The x intercepts are 0 when the object was thrown and 2 when it landed
The x coordinate of the vertex is in the middle of the two x intercepts so it will be 1
Substituting the x coordinate of the vertex gives us the y coordinate of the vertex which is the maximum hight 16
