Graphing and Interpreting Quadratic Functions:
The height of a football thrown from the deck of a ship can be modeled by
h=(-4t - 4)(4t - 20) where h is the height of the ball above water in feet and t is the time in seconds.
Find the number of seconds it takes the flare to hit the water.
How many seconds does it take to reach its highest point?
Graph the function to answer the question.
Connecting intercepts and factors
Graph the Function y=(x + 6)(x - 1)
Where does the parabola intercept (cross) the x-axis?
x=
