Standard Form
This is the general formula for the standard form of a quadratic function.
What is ax2+bx+c?
These are the x-intercepts of the function f(x)=4x2+20x+25
x1= -5/2. x2= -5/2
This is the general formula for the vertex form of a quadratic function.
What is a(x-h)2+k?
On a graph, the vertex is also referred to by two other names depending on the function.
What is maximum and minimum?
This is the transformation from the parent graph f(x) = x2 to the function g(x) = (x + 2)2 + 8.
What is left 2 and up 8?
This is the direction this quadratic function opens: f(x)=3x2+5x-1.
What is up?
This is the transformation from the parent graph f(x) = x2 to the function g(x) = (x - 2)2 - 8.
What is right 2 and down 8?
This is the vertex of this quadratic function:
(x-4)2+5
What is (4,5)?
This form of a quadratic function is the easiest to find the y-intercept. x2+4x+3=0
This is the vertex of the following quadratic: f(x) = (x -9)2 - 9
What is (9, -9)?
This is the y-intercept of the function: f(x)=-5x2+3x-6
What is (0,-6)?
These are the x-intercepts of the function f(x)=(x-2)(x+15).
What is (2 ,0) and (-15,0)?
This is the transformation from the parent graph f(x) = x2 to the function g(x) = (x + 7)2 - 3.
What is left 7 and down 3?
This form is the easiest to find the x-intercepts of a quadratic function.
What is factored form?
Find vertex of each quadratic function y=3x2 -6x +2
1
This is the formula we use to find the Axis of Symmetry for a function written in Standard Form.
What is x =-b/2a ?
This is the equation of a quadratic that has x-intercepts at (-8, 0) and (1, 0).
What is f(x) = (x + 8)(x - 1)?
When this quadratic function -1/2(x-7)2+12 is graphed, it opens in this direction.
What is down?
This form of the quadratic function is the easiest to find the vertex.
-b/2a
This will determine if a quadratic function opens up or down.
What is the "a" value?
These are the values of a, b, and c in the function: f(x) = x2 - 7x + 9
What is a = 1, b = -7, c = 9?
This is the vertex of the function: f(x)=(x - 4)(x - 3)
What is (3.5, -0.25)?
This is the equation of a quadratic function with the transformations: up 8 right 4
f(x) = (x + 4)2 +8?
True or False: The Domain of quadratic functions is:
(-infinity, + infinity).
What is true?
This is the equation of a quadratic function with the transformations: up 7 right 2.
What is a f(x) = (x - 2)2 +7?
