Directions:

1. This will be turned in so show your work neatly! NO TALKING ALLOWED!!!

2. Work each problem on your own paper.

(Bingo directions to follow after the problems.)

### 1. Convert to standard form:y = (x+3)² - 2

2. Covert to vertex form:y = x² + 2x – 4

3. Factor:2s² + 5s - 3

4. Solve (by any method)x² + 3x +4 = 0

6. Solve:3(x +2)² + 4 = 16

7. What is the range of the graph for this equation?(Hint: graph it!)y = -3x² + 6x + 3

minimum value of

the function? Where

does the min occur?

As x→-∞ , f(x) → ___

and

As x→+∞ , f(x) → ___

y = -2 (x-2)² - 4

2x² - 15x = -7

y = -3x² +5x -6 ?

13. Is (4,-3) a solution for the equation

y ≤ ½ x² + 5x + 3 ?

5x² - 5x = -5

X + 4

X - 3

2x² - 5x -4 ≥ 0

Y = -2(x+5)² -5?

19. Describe the equation value of the discriminantof the function whose graph is shown here. (hint: positive, negative, or zero)

22. Solve equation the equation:

2x² + 8 = 0

23. Factor equation .

5x² - 2x - 3

24. Write equation in vertex form:

y = x² + 6x - 5

Now take each of the answers you got and write them in one of the boxes on you BINGO card. Use each answer only once! Your card must be completely filled in order to play the game. If you didn’t finish a question, then put an “X” in a box. That box won’t be used to play the game. Put your name on your paper and turn it in now!

An answer will appear on the screen. If you have that answer on your sheet put a check mark on it. Once you get 5 answers in a row marked, call out “BINGO”. Once your answers are verified you will receive a prize. ALL ANSWERS MUST BE WRITTEN THE WAY THEY APPEAR ON THE SCREEN TO BE CORRECT. (ex. X=3 not just 3)
