f(x) = -x2 - 4x + 12
y = 5x2 - 20x + 13
f(x) = -2x2 + 4x - 6
The standard form of a quadratic function is
ax2 + bx + c
a(x - h)2 + k
y - y1 = m(x - x1)
Ax + By = C
If a is negative in the function, which way does the parabola
up
down
left
right
y=ax2+bx+c
Given the equation y = 3(x + 5)2 - 4,
what is the vertex of the parabola?
(5, -4)
(-5, -4)
(-15, -4)
(15, -4)
Given the equation: y = -(x - 4)2 - 3,
does this parabola have a maximum or minimum value?

Minimum
The axis of symmetry line passes through which point?
y-intercept
any random point
vertex
symmetrical point for the vertex
y = 3(x + 5)2 - 4, what is the vertex of the parabola?
(5, -4)
(-5, -4)
(-15, -4)
(15, -4)
If the blue graph is f(x) = x2
then the red must be...
g(x) = x2 - 5
g(x) = x2 + 5
g(x) = (x - 5)2
g(x) = (x + 5)2
Tammy solved the equation x2−x−12=0
Select the factors of x2−x−12
(x+3)(x+4)
(x-3)(x-4)
(x+6)(x-2)
(x-6)(x+2)
(x+3)(x-4)
What are the x-intercepts of the parabola?
y = x(x - 4)
(0, 0) and (4, 0)
(1, 0) and (4, 0)
(0, 4)
(-4, 0) and (0, 0)
In f(x) = a(x - p)(x - q), what does "a" tell us?
The slope
If the Parabola opens up or down
x coordinate of the x - intercept
y coordinate of the y - intercept
Solve 2x² - 7x + 6 = 0 by factoring
x = -3/2 and x = -2
x = -3 and x = -2
x = 3 and x = 2
x = 3/2 and x = 2
The solution, root, x-intercept, and zero of a problem are all the same thing.
