Miscellaneous
100
This is the type of graph that a quadratic function forms.
Parabola
100
This is the general form of a quadratic function.
ax² + bx + c
100
This is the maximum number of x-intercepts a quadratic function can have.
Two
100
In order for a quadratic function to be thinner, a regular fraction must be substituted for this coeffiecient. (a, b or c?)
a
100
These are the values that are listed as the domain of a quadratic function.
x-values
200
If the variable a>0, then the graph opens in this direction.
Upward
200
This is the number of forms a quadratic equation can be written in.
Three
200
This is how you find y-coordinates for a point in a quadratic equation.
Substitute in x and solve for y
200
Thinner
If a>1, then is the graph going to be wider or thinner?
200
This is the form represented by y=a(x-p)(x-q), when the x-intercepts are shown by the variables p and q.
Factored or Intercept Form
300
The axis of a parabola is parallel to this axis.
Y-axis
300
This is the power that the variable in a quadratic function is raised to.
Second
300
This is the y-intercept for the quadratic function y=5x² + 6x + 1.
1
300
This is the most basic quadratic function.
y=x²
300
This is the vertex form of a quadratic function.
y=a(x-h)² +k
400
In this situation, the quadratic function is a reflection over the x-axis.
a<0
400
These are what the letters a, b, and c in a quadratic funtion are called.
Coefficients
400
This is what the vertex of the graph is called when the coefficient a>0.
Minimum Value
400
These are the coordinates in the equation y=2x²-x-4 if x=-2.
(-2,6)
400
This is the some of three monomials.
Trinomial
500
This is the what the highest or lowest point on a parabola is called.
Vertex
500
This is the form used to find the x-intercepts (or 'zeros') of a function.
Factored Form
500
These are different names for zeros of a function.
Roots or x-intercepts
500
These are the zeros (x-ints) of the function (x+1)(x-4).
-1 and 4
500
This is the process to change a quadratic function in factored form back to general form.
