Yes
No
Which set of ordered pairs is a function?
{(9,5), (10,5), (9,-5), (10,-5)}
{(3,4), (4,-3), (7,4), (3, 8)}
{(6,-5), (7, -3), (8, -1), (9, 1)}
{(2, -2), (5, 9), (5, -7), (1, 4)}

Does this table represent a function?
Yes
No
x2 + 4x= 12
(x + 2)(x - 3) = 0
Solve by factoring
-4, 2
-2, 4
-16
-4
Solve using the Quadratic Formula:
2x2 + 2x − 12 = 0
x = −2, 3
x = 2, 3
x = 2, −3
x = −2, −3
Solve by factoring. (HINT: Factor GCF 1st)
x = 3, x = -6
x = 0, x = 2
x = 2, x = 3
x = -2, x = 1
3x2 + 18x +15
x4-9x2
f(x) = 2(x - 5)2 + 12
y = -2x2 + 4x + 3
f(x) = x2 - 8x + 15.
y = 3x2 - 6x + 4
The root, x-intercept, and zero are all the same thing
f(x) = -x2 - 4x + 12.
f(x) = 2(x - 5)2 + 12
f(x) = -2x2 + 4x - 6
f(x) = x2 + 6x + 5
x2 + 13x + 12 = 0
x2 + 4x= 12
Does y = -5x2 + 10x - 14 have a maximum or minimum?
minimum
maximum
Does the equation y = -3x2 + 7x - 2 open up or down?
up
down
