About This Chapter
Functions as Models - Chapter Summary
As you make your way through these mobile-friendly lessons on functions as models, you'll verify your understanding of how quadratic functions are used to model a situation. During your studies, you'll gain a deeper understanding of what's involved in modeling with rational functions. After completing the chapter, you should be ready to:
- Discuss how exponential and logarithmic functions are used in modeling
- Explain how to model situations using linear and exponential functions
- Provide an overview of rational equations used in modeling
- Describe what's involved in modeling with polynomial functions
- Model a data set using quadratic functions
Our online learning platform offers the flexibility of studying when it's most convenient for you. Each lesson is accompanied by a brief quiz to assess how much you can recall about functions as models. If you end up struggling with a topic, you can use the Help feature to send questions to experts. You can even print the quiz as a helpful offline study tool.
1. Using Linear & Exponential Functions to Model Situations
Linear and exponential functions can both be used to model data. In this lesson, learn about these two important functions and how and when to use each one.
2. Modeling with Exponential & Logarithmic Functions
This lesson will give a quick review of exponential and logarithmic functions and when to use these functions to model data. Then we will explore the use of graphing calculators in finding exponential and logarithmic functions to model given data.
3. Modeling With Rational Functions & Equations
In this lesson you will learn about rational functions, discontinuities and how we can use them to model real-life scenarios. Some examples will include average cost, percentage and mixture problems.
4. Using Quadratic Functions to Model a Given Data Set or Situation
Watch this video lesson to learn how quadratic functions are used to model situations and data gathered from real world scenarios. See how our function fits our data and situation well.
5. Modeling with Polynomial Functions
Modeling real-world phenomena with a function is an extremely useful tool to have at our disposal. This lesson will explain how to model a given set of data points with polynomial functions using the method of finite differences.
