The Difference Between Relations & Functions

1. The Difference Between Relations & Functions

Relations and functions are a huge part of mathematics. In this lesson, we will define relations and functions. We will look at the differences between the two and how to determine whether a given relation is a function.

Algebraic Function: Definition & Examples

2. Algebraic Function: Definition & Examples

An algebraic function is a type of equation that uses mathematical operations. An equation is a function if there is a one-to-one relationship between its x-values and y-values.

Determining Inputs & Outputs of Functions

3. Determining Inputs & Outputs of Functions

Functions are like the manufacturing plants of mathematics: One thing goes in, another comes out. In this lesson, we'll discuss how to determine the inputs and outputs of functions that show up as tables, graphs, or algebraic expressions.

What is a Linear Function? - Definition & Examples

4. What is a Linear Function? - Definition & Examples

In this lesson, you will learn the key identifying mark of linear functions. You'll also learn how to graph them with just two points and how you can use the graph to easily find your answers.

Interpreting the Slope & Intercept of a Linear Model

5. Interpreting the Slope & Intercept of a Linear Model

You've probably seen slope and intercept in algebra. These concepts can also be used to predict and understand information in statistics. Take a look at this lesson!

Nonlinear Function: Definition & Examples

6. Nonlinear Function: Definition & Examples

In this lesson, we will familiarize ourselves with linear functions in order to define and understand what nonlinear functions are. We will become comfortable determining if a function is linear or nonlinear through definitions and examples.

Determining Intercepts for Nonlinear Functions

7. Determining Intercepts for Nonlinear Functions

This lesson will define linear and nonlinear functions. We will then go on to explore the intercepts of nonlinear functions and look at how to identify them graphically and algebraically using a real-world example.

How to Identify Families of Functions

8. How to Identify Families of Functions

Functions come in all kinds of varieties, but they can be grouped together into families that have common characteristics. The difference and similarities can be seen in the equations and graphs of these functions. In this lesson, you will learn about the characteristics of different families of functions and how to recognize them based on their equations and graphs.

Compare Properties of Functions Numerically

9. Compare Properties of Functions Numerically

Can you compare functions when they're written out numerically as tables of values? In this lesson, you'll learn to do just that and to compare one function as a table to another written in a different form.

Compare Properties of Functions Algebraically

10. Compare Properties of Functions Algebraically

In this lesson, we will explore algebraic and numeric properties and the evaluation of functions. We'll demonstrate function evaluations and the idea that every element of the domain has a unique element in the range.

Compare Properties of Functions Graphically

11. Compare Properties of Functions Graphically

In this lesson, we will cover the characteristics of graphs of functions. We will employ the vertical line test and understand why some graphs do not qualify as functions.

Describe the Functional Relationship Between Quantities

12. Describe the Functional Relationship Between Quantities

In this lesson, you'll learn how to look at a graph, table, or function written mathematically and verbally describe the functional relationship shown. For example, you'll learn to describe whether the function is increasing or decreasing.
