Row 1, Col 1

Use the discriminant to determine the number of solutions the quadratic

will have.

1,2

Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height as a

function of time could be modeled by the function h(t) = −16t2 +16t + 480,

where t is the time in seconds and h is the height in feet. What is the maximum height of Jason’s jump?

1,3

Solve the system by graphing.

1,4

Write the equation given the data

x y-2 5-1 20 11 22 5

2,1

Write the quadratic equation that goes with this formula.

2,2

Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height as a

function of time could be modeled by the function h(t) = −16t2 +16t + 480,

where t is the time in seconds and h is the height in feet. When will Jason hit the water?

2,3

Sketch the graph andmark the solutions.

2,4

Write the equation given the points.(-2, 5) (-1, 3) (0, 5) (1, 11) (2, 21)

3,1

Solve using the quadratic formula.

3,2

Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height as a

function of time could be modeled by the function h(t) = −16t2 +16t + 480,

where t is the time in seconds and h is the height in feet. How high is Jason after 1.2 seconds?

3,3

Solve the system by any method.

3,4

Write the quadratic equation.

4,1

Solve using the quadratic formula.

4,2

Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height as a

function of time could be modeled by the function h(t) = −16t2 +16t + 480,

where t is the time in seconds and h is the height in feet. What is the height of the cliff that Jason jumped off of?

4,3

Solve the system by substitution.

4,4

Write the quadratic equation.(1, 6) (2, 3) (3, 2) (4, 3) (5, 6)

5,1

Solve using the quadratic formula.

5,2

Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height as a

function of time could be modeled by the function h(t) = −16t2 +16t + 480,

where t is the time in seconds and h is the height in feet. How long did it take for Jason to reach a height of 482 ft?

5,3

Solve the system using substitution.

5,4

Write the equation for the graph given.
