Ch 25: Praxis Middle School Math: Graphing Functions

About This Chapter

In this chapter, you'll become acquainted with different methods for graphing functions, so you can effectively study for these types of questions on the Praxis Middle School Mathematics exam.

Praxis Middle School Math: Graphing Functions - Chapter Summary

The lessons in this chapter will address the proper mechanisms for graphing functions. By the end of this chapter you will have reviewed:

  • Plotting points
  • Graphing cubics, quartics, quintics and more
  • Identifying the direction of a function
  • Finding the slope and intercepts of a line
  • Using the point-slope formula
  • Parabolas
  • Standard, intercept and vertex parabolas

The lessons in this chapter have been designed to review information regarding the graphing of functions that you are likely to come across on the Praxis Middle School Math exam. Each lesson contains a short video to visually exhibit the material. A transcript of the video is included as a great resource for taking notes. You can take a self-assessment quiz at the end of each lesson to test your knowledge and see how questions may appear on the exam.

Graph Functions by Plotting Points

1. 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.

How to Graph Cubics, Quartics, Quintics and Beyond

2. How to Graph Cubics, Quartics, Quintics and Beyond

Finding the graph of a polynomial isn't too hard. If you can graph, you already know the major steps! With a couple rules and helpful memorizing tools, you will be graphing polynomials in no time!

Identify Where a Function is Linear, Increasing or Decreasing, Positive or Negative

3. Identify Where a Function is Linear, Increasing or Decreasing, Positive or Negative

Functions do all kinds of fun things. In this lesson, learn how to identify traits of functions such as linear or nonlinear, increasing or decreasing and positive or negative.

How to Find and Apply The Slope of a Line

4. 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

5. 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.

Equation of a Line Using Point-Slope Formula

6. Equation of a Line Using Point-Slope Formula

It's time for a road trip to Las Vegas, and after four hours of driving at 60 mph ... Are we there yet? Learn the point-slope form of the equation of a line to help answer this age-old question.

What is a Parabola?

7. 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.

Parabolas in Standard, Intercept, and Vertex Form

8. 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.
