Question

david throws a ball up in the air. the graph below shows the height of the ball h in feet after t seconds. what is the balls greatest height?
(0.75, 9)
(1.5, 0)
height (in feet)
time (in seconds)
answer
feet

Explanation:

Step1: Identify the vertex

The graph of the ball's height is a parabola, and the highest point (vertex) is given as \((0.75, 9)\).

Step2: Determine the greatest height

The \(y\)-coordinate of the vertex represents the maximum height. Here, the \(y\)-coordinate is \(9\).

Answer:

9
