Quadratics and Functions

1. Binomials: Quadratics with two terms.

1.1. Trinomials: Quadratics with three terms

1.1.1. Polynomials: Quadratics with multiple terms

1.2. Factoring: a method for simplifying polynomials

2. Imaginary Unit: a different solution to the quadratic equation

3. Radical Function: a function whose rule is a radical exponent.

3.1. Square Root Function: a radical function involving the square root of x

3.2. Standard Form: another way to write a quadratic functions

3.2.1. Zero of a Function: the input x that makes y equal zero.

3.3. Roots of the Equation: variables in the equation that make it true

4. Quadratic Function: a function written as y= square root of x

4.1. Parabola: a u shaped curve made by a quadratic function

4.1.1. Axis of symmetry: a line through the parabola's vertex

4.2. Maximum Value: the y value when the parabola opens downward

4.2.1. Minimum Value: the y value when the parabola opens upward

4.2.2. Vertex: the high endpoint of the parabola

4.2.2.1. Y-intercept: the point where the parabola crosses the y axis.

4.2.2.1.1. Domain: all the x values in the graph
