Using Tables and Graphs in the Real World

1. Using Tables and Graphs in the Real World

Tables represent data with rows and columns while graphs provide visual diagrams of data, and both are used in the real world. Explore tables, graphs, and examples of how they are used for common things, such as explaining a cell phone plan and charting population growth.

Scatterplots and Line Graphs: Definitions and Uses

2. Scatterplots and Line Graphs: Definitions and Uses

Scatterplots and line graphs are mathematical representations used to visually analyze and interpret data. This lesson defines scatterplots and line graphs, identifies when to use each, and provides examples of their various uses.

What is a Parabola?

3. What is a Parabola?

A parabola is a U shape that is created when a quadratic equation is graphed. Explore the characteristics of parabolas, how they are used in everyday life, and the defining spots of a parabola.

Parabolas in Standard, Intercept, and Vertex Form

4. Parabolas in Standard, Intercept, and Vertex Form

The equation of a parabola can be expressed in three different forms. Explore different kinds of parabolas, and learn about the standard form, the intercept form, and the vertex form of parabola equations.

Multiplying Binomials Using FOIL and the Area Method

5. Multiplying Binomials Using FOIL and the Area Method

The FOIL method and the area method are two ways of multiplying binomials. Explore binomials and learn how to multiply binomials using the FOIL method, the area method, and the claw and face method.

Multiplying Binomials Using FOIL & the Area Method: Practice Problems
