Michael threw a ball into the air from the top of the building. The height of the ball, in feet, is modeled by the equation (where t is time measured in seconds). What is the meaning of the vertex in the context of the problem? (Vertex is 2,144)

It is already telling you the vertex, it just wants to know what you think this represents.

Step-by-step explanation:

Read the first sentence again, he is throwing a ball. Then the second sentence says the equation is the height of the ball, so you know the vertex has to do with the height of the ball. How do you think that height would compare with the other heights of the ball? Would probably be obvious if you sketched a little picture of the graph:)
