Math 2 unit 2
Axis Of Symmetry
A line that goes down the middle of the parabola and intersects the vertex
Quadratic Inequalities
A quadratic inequality is just like a quadratic equation, except instead of an equal sign there's an inequality
Quadratic Formula
Formula to find the zeroes of a quadratic equation.
Imaginary Number/ Complex Solution
If a quadratic equation with real-number coefficients has a negative discriminant, then the two solutions to the equation are complex conjugates of each other.
Completing the Square
Process to find the zeroes of a quadratic equation.
Standard Form
The standard form of a quadratic is y = ax ^2 + bx + c, where a, b, and c are numbers and a cannot be 0.
Vertex Form
The vertex form of a quadratic equation is written like f (x) = a(x - h)2 + k, with the letter h and the letter k being the vertex point of the parabola. It can be used to create an equation when the vertex of the parabola is known, but other points are not.
Maximum
The vertex if the parabola opens down.
Minimum
The vertex if the parabola opens up.
X value of X- intercept
Zeroes, roots, solutions,
