Instructions for using this template. Remember this is Jeopardy, so where I have written Answer this is the prompt the students will see, and where I have Question should be the students response. To enter your questions and answers, click once on the text on the slide, then highlight and just type over whats there to replace it. If you hit Delete or Backspace, it sometimes makes the text box disappear. When clicking on the slide to move to the next appropriate slide, be sure you see the hand, not the arrow. (If you put your cursor over a text box, it will be an arrow and WILL NOT take you to the right location.)

Choose a category. You will be given a question. You must provide the correct answer. Click to begin.

Which way does the graph y = -6x 2 + 2 open?

down

Where is the axis of symmetry for the graph of y = 2x 2 + 4?

X = 0

Where is the axis of symmetry for the graph of y = 4x 2 + 4x -2?

X = - 1/2

Find the axis of symmetry and vertex for the graph y = -3x 2 + 3x - 1

x = ½ (1/2, -1/4)

Find the vertex and axis of symmetry for y = 4 + 8x – 2x 2

X = 2 (2, 12)

Solve for x (x+2)(x-4) = 0

x= -2 or 4

Solve: x 2 + 3x + 2 = 0

x = -1 or -2

Solve: 2x 2 + 5x + 3 = 0

X = -1 or -1.5

Solve: 5x 2 – 68x = 192

X = 16 or -2.4

Solve and round to the nearest hundredth 2x 2 – 24x + 33 = 0

X = 10.42 or 1.58

Suppose you throw a ball upward and the equation h = -16t 2 +30t + 6 models the path the ball takes where h is the height of the ball and t is time in seconds. After how many seconds will the ball hit the ground?

Suppose a rectangle has an area of 60 ft 2 and dimensions x and (x + 1). Find the dimensions of the rectangle to the nearest hundredth.

7.26 ft x 8.26 ft

A rectangle has a length of x. Its width is 3 feet longer than twice the length. Find the dimensions if its area is 80 ft 2. Round to the nearest tenth of a foot.

5.6 ft by 14.2 ft

An apartment rental agency uses the formula I = 5400 + 300n – 50n 2 to find its monthly income I based on renting n apartments. Will the agencys monthly income ever reach \$7000? Explain.

No, the discriminant is negative (300 2 – 4 (-50)(-1600) = -230,000)

For the equation x 2 + 2x + k = 0; find the value of k to the equation has one solution

k = 1

How many solutions does x 2 – 6x + 9 = 0 have?

One (discriminant = 0)

How many x-intercepts does x 2 – 2x – 3 = 0 have?

2 (discriminant = 16)

The function P = 3i 2 – 2i + 450 models the power P in an electric circuit with a current i. Can the power in this circuit ever be zero? If so, what is the value of i?

No, the discriminant is -5396.

How many zeros does the equation 2x 2 – 3x + 4 = 0 have?

None, the discriminant is -23.

Does the graph of the function cross the x- axis? y = 4x 2 + x - 5

Yes, twice. The discriminant is 81.
