Ch 17: MTEL Middle School Math/Science: Functions

About This Chapter

With this chapter, prepare for questions on the MTEL Middle School Math/Science exam that will test your skills graphing and comparing properties of functions, including linear functions.

MTEL Middle School Math/Science: Functions - Chapter Summary

These lesson videos have been assembled to help you improve your abilities working with algebraic functions. In them our professional instructors will demonstrate how to graph equations and identify their properties so that you can then compare them. From these lessons you should improve your knowledge and skills related to:

  • Identifying properties of functions
  • Plotting points to graph functions
  • Algebraically and graphically comparing properties of functions
  • Finding and applying the slope and intercepts of a line
  • Composing a function
  • Modeling linear relationships
  • Determining rate of change of functions

In addition to watching these videos, you can read the lesson transcripts for written overviews that may prove helpful when trying to comprehend the terms and figures of the chapter. Then test your understanding of the subjects presented by taking the lesson quizzes. The results from these quizzes will not only inform you of the topics you didn't master but also provide you with video tags that you can use to return to the locations of the lessons that discussed them and improve your understanding of the material.

What is a Function: Basics and Key Terms

1. What is a Function: Basics and Key Terms

Mapping numbers sounds complex, but we do it when we buy gasoline. We pump gasoline, and the gas station charges us based on the amount of gas that we pump. Learn how this relates to functions while reviewing the basics and notations in this lesson.

Functions: Identification, Notation & Practice Problems

2. Functions: Identification, Notation & Practice Problems

A function is simply a rule that takes one number and turns it into another. But some special conditions must apply for it to be a true mathematical function. Learn about those conditions and how we write functions here!

Graph Functions by Plotting Points

3. Graph Functions by Plotting Points

Let's say you have a function. What does it look like? How do you graph it? In this lesson, we'll learn how to graph functions by determining and plotting points.

Compare Properties of Functions Algebraically

4. 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

5. 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.

How to Find and Apply The Slope of a Line

6. How to Find and Apply The Slope of a Line

In this lesson, we'll discover all about the slopes of lines. We'll learn about different types of slopes and how to find the slopes of lines. We'll use two methods: the slope formula and the slope-intercept form.

How to Find and Apply the Intercepts of a Line

7. How to Find and Apply the Intercepts of a Line

How can you take an equation of a line and find out where it will cross the x- or y-axis? In this lesson, we'll define x-intercepts and y-intercepts and learn how to find them.

How to Compose Functions

8. How to Compose Functions

Function composition is the process of putting two or more functions together. This video lesson will explain how this process works and also show you how to evaluate functions that have been composed.

Model a Linear Relationship Between Two Quantities

9. Model a Linear Relationship Between Two Quantities

In this lesson, we will learn about modeling linear relationships by converting domain and range values into ordered pairs and then constructing a graph.

Determine the Rate of Change of a Function

10. Determine the Rate of Change of a Function

In this lesson, we will learn about the rate of change of a function with specific focus on linear and exponential functions while examining the graphs of both types of functions.
