Step-by-step explanation:

A baseball player hits a ball. The table represents a quadratic function that shows how the height of the ball changes over time.

Time (s) Height (ft)

0 5

0.25 8

0.50 9

0.75 8

1.00 5

1.25 0

To find the y coordinate of vertex, first we find the vertex point from the given table

after and before x=0.50 the value of y is 8 and it starts decreasing so the vertex point is (0.50,9)

the y coordinate of vertex is 9. It represents the maximum height .

the maximum height, in feet, that the ball reaches

Step-by-step explanation:

I just took the test, but also there is no other point that is higher than that point, which means that it is indeed, the highest point.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
