Question

Julie tips the ball over the net in a volleyball game. The graph shows the quadratic function that represents the height of the ball, in feet, when it is a horizontal distance of x feet from Julie.
A)14 feet
B)6 feet
C)3 feet
D)3.5

Answer 1

We are given a graph for the height of the ball with respect to horizontal distnace x of the ball from Julie.

From the graph, we can see the position of Julie is at (0,0). And starting height of the ball when thrown is 6 feet.

Then it moved to the maximum height of 14 feet. And hit to the ground when it has position on x-axis is 3.5 feet.

Because we can see the parabola is crossing x-axis at 3.5 on the right.

That represents distance of the ball from Julie when it hit to the ground.

Therefore, it has a horizontal distance of 3.5 feet from Julie.
