Graphing Quadratic Functions
A ball is thrown vertically into the air with a velocity of 112 feet per
second. The ball was released 6 feet above the ground. The height
above the ground t seconds after release is given by the formula
h 16t 2 112t 6.
1. Complete the table
using whole-number
values for t.

2. Use the values in the
table to graph the
equation representing
the height of the ball.
Height (feet)
O
Time (seconds)
t
3. What is the maximum height the ball achieves? Explain how you know.
4. How long did it take the ball to return to the ground?
