1. What is a Parabola?
A parabola is the U shape that we get when we graph a quadratic equation. We actually see parabolas all over the place in real life. In this lesson, learn where, and the correct vocab to use when talking about them.
2. Parabolas in Standard, Intercept, and Vertex Form
By rearranging a quadratic equation, you can end up with an infinite number of ways to express the same thing. Learn about the three main forms of a quadratic and the pros and cons of each.
3. Vertex Form: Equation & Functions
Just as y = mx + b is a useful format for graphing linear functions, y = a(x - h)^2 + k is a useful format for graphing quadratic functions. We will explore its uses and learn how to convert any quadratic equation into vertex form.
4. Even & Odd Functions: Definition & Examples
Even and odd functions are an aspect of line symmetry. You can use knowledge of even and odd functions to quickly identify equation symmetry. After this lesson, test your knowledge with a short quiz!
5. Find the Axis Of Symmetry: Equation, Formula & Vertex
This lesson discusses how to locate the axis of symmetry of a parabola in the standard x-y coordinate plane. Learn how the vertex of the parabola relates to its axis of symmetry and how to determine the axis of symmetry from a quadratic equation.
6. Parabola Intercept Form: Definition & Explanation
In this lesson, we will define a parabola, discover its everyday uses, determine the functions of the intercept form of the equation, and find the x-intercepts of a parabola.
7. Comparing Linear, Exponential & Quadratic Functions
In this lesson, we will use a real-world scenario to compare linear, exponential, and quadratic functions. We will look at how they differ algebraically and graphically as well as what types of patterns each of them take on.
