1.
The U-shaped graph of a quadratic function.
2.
The highest (maximum) or lowest (minimum) point on the parabola.
3.
A vertical line that divides the parabola into two mirror images; it always passes through the vertex.
4.
The y-coordinate of the vertex if the parabola opens downward
5.
The y-coordinate of the vertex if the parabola opens upward
6.
The points where the parabola crosses the x-axis; also called roots, zeros, or solutions.
7.
The point where the parabola crosses the y-axis
8.
The most basic quadratic function from which all quadratics are transformed
9.
A transformation that flips the parabola over a line, such as the x-axis, typically caused by a negative leading coefficient.
10.
A transformation that stretches or compresses the parabola vertically, making it narrower or wider.
11.
A function with a second-degree polynomial, commonly written as f(x)=ax^2+bx+c
12.
A quadratic written as f(x)=ax^2+bx+c where (h,k) is the verex
13.
Commonly written as f(x)=a(x-p)(x-q) where x and p are the x intercepts
14.
the constant a in ax^2+bx+c that determines the parabola's direction and width.
15.
The value c in standard form which also represents the y-intercept of the graph
16.
A method of solving quadratics by turning a trinomial into a perfect square trinomial.
17.
The formula used to find the roots of any quadratic equation.
18.
A trinomial that factors into two identical linear factors
19.
The x-values that make the function equal to zero
20.
A number in the form a+bi, where i is te imginary unit.
