Quadratic BINGO
Directions:
1. This will be turned in so show your work
neatly! NO TALKING ALLOWED!!!
2. Work each problem on your own paper.
3. Circle your answer.
(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
5. Find the vertex for the equation:
y = -2x² + 4x +5
6. Solve:
3(x +2)² + 4 = 16
7. What is the range of the graph
for this equation?
(Hint: graph it!)

8. What is the
minimum value of
the function? Where
does the min occur?
9. Describe the end behavior of the graph:
As x→-∞ , f(x) → ___
and
As x→+∞ , f(x) → ___
10. Convert to standard form:
y = -2 (x-2)² - 4
11. Solve (by any method):
2x² - 15x = -7
12. What is the domain of the graph of

X+4
X-3
16. What is the
interval of
increase for the
graph?
17. Solve algebraically.
2x² - 5x -4 ≥ 0
(write answer as an inequality)
18. What is the axis of
symmetry for the graph of
the equation
Y = -2(x+5)² -5?
19. Describe
the value of
the
discriminant of
the function
whose graph is
shown here.
(hint: positive,
negative, or
zero)
20. What is
the interval
of decrease
of the
graph
shown?
21. Which of the
following inequalities
is graphed here?
a. y ≥ -x² + 4x -3
b. y > -x² + 4x -3
c. y < -x² + 4x -3
d. y ≤ -x² + 4x -3
22. Solve the equation:
2x² + 8 = 0
23. Factor.
5x² - 2x - 3
24. Write 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)
(1,7)
Y = (x + 3)² - 14
(-∞, 6]
X = 0 , -4
( -∞, +∞)
X=7
( 5x + 3)( x – 1 )
( -∞, 1)
X = ± 2i
( -4,+∞)
Y = -2x² + 8x - 12
+∞
+∞
X = -5
Min Value = -3
@ x =-4
x² + 6x +7
Y = (x + 1)² - 5
Negative
B
X < -½ or x > 3
Yes, it is a
solution
X = ½, 7
