Ch 25: MTTC Math (Secondary): Graphing Functions

About This Chapter

Use this chapter to improve your skills graphing functions, identifying the properties of functions and using equations of functions when graphing as you prepare for the MTTC Mathematics (Secondary) exam.

MTTC Math (Secondary): Graphing Functions - Chapter Summary

When studying for the MTTC Mathematics (Secondary) test, complete the activities of this chapter to improve your skills graphing functions. Follow along with our expert instructors in a series of lesson videos as they demonstrate how to plot points to graph functions, identify and apply the properties of functions and use the equations of functions when graphing. After these lesson videos you should have a better understanding of:

  • Plotting points to graph functions
  • Identifying and applying linear properties of functions
  • Using the point-slope formula, distance formula, and midpoint formula
  • Standard, intercept and vertex forms of parabolas
  • Graphing inverse functions
  • Graphing functions of functions
  • Even vs. odd functions

In addition to watching these lesson videos, complete the assessments that accompany them to reinforce your understanding of the material presented and find areas of weakness. Fortify your understanding of your areas of weakness by returning to the lesson videos with videos tags, or for an alternative review you can read over the lesson transcripts.

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.

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

2. 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

3. 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

4. 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

5. 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.

How to Use The Distance Formula

6. How to Use The Distance Formula

You can't always rely on your smartphone to tell you how far you need to travel to get from point A to point B. The distance formula will tell you the distance between any two points on a graph. In this lesson, you'll learn where it comes from and how to use it!

How to Use The Midpoint Formula

7. How to Use The Midpoint Formula

The formula for the midpoint of a line segment will tell you how to find the middle of any line segment on the x, y plane. Learn about this formula and see how it is used to find the midpoint of a line segment.

What is a Parabola?

8. 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

9. 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.

Understanding and Graphing the Inverse Function

10. Understanding and Graphing the Inverse Function

If you use a function to map a to b, is there a way to go back from b to a again? Learn how to find and graph inverse functions so that you can turn a into b and back into a.

Compounding Functions and Graphing Functions of Functions

11. Compounding Functions and Graphing Functions of Functions

We know that functions map numbers to other numbers, so what happens when you have a function of a function? Welcome to functions within functions, the realm of composite functions!

Even & Odd Functions: Definition & Examples

12. 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!
