Students will review:
In this chapter, you'll learn the answers to questions including:
- How do I graph functions of functions and the inverse function?
- What steps do I follow when factoring and simplifying in polynomials functions?
- How do I define and calculate slopes and tangents on graphs?
- What do I do to find horizontal and vertical asymptotes?
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.
2. Graphing Basic Functions
Graphs are just like maps - when you know the language! Review how locations have x and y coordinates similar to latitude and longitude, and how to plot points in the Cartesian plane.
3. 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!
4. 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.
5. Polynomial Functions: Properties and Factoring
Everything from projectile motion to trigonometric functions can be described by polynomials. Review factoring, polynomials and quadratic functions in this lesson.
6. Polynomial Functions: Exponentials and Simplifying
How do we keep track of a rapidly multiplying population of bunnies? Well, those are simply powers of 2. Review powers and simplify problems with exponents in this lesson.
7. Exponentials, Logarithms & the Natural Log
Use the properties of exponentials and logarithms to learn how carbon dating works. This lesson covers properties of a natural log and rules of logarithms.
8. Slopes and Tangents on a Graph
Hit the slopes and learn how the steepness of a line is calculated. Calculate the slopes between points and draw the tangents of curves on graphs in this lesson.
9. 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.
10. Horizontal and Vertical Asymptotes
No matter how hard you try to get to them, asymptotes remain out of reach. Learn about these invisible lines on graphs that show you places your equations just can't go.
11. Implicit Functions
Sometimes inputting a variable into a function 'black box' doesn't yield a simple output. Find out what happens when you can't isolate the dependent variable on one side of the equal sign.
12. Normal Line: Definition & Equation
In calculus, a normal line is a line that goes through a point on a curve and is perpendicular with the tangent line at that point. In this lesson, you'll learn more about normal lines and how to find their equations.
13. Point of Intersection: Definition & Formula
In this lesson, we'll learn what the point of intersection is and how to find it graphically and algebraically. This concept applies to lots of other areas of study, including business, finance, construction and physics.
14. Point Slope Form: Definition, Equation & Example
In this lesson, you will learn the definition and formula for writing the equation of a line in point-slope form. Then, we will look at a couple of examples. At the end, you will be able to test your knowledge with a quiz.
15. Point Symmetry: Definition & Examples
Symmetry is a common occurrence and concept of nature and life. In this lesson, we will look particularly at the characteristics of objects that have point symmetry.
16. Polar Coordinates: Definition, Equation & Examples
Discover a new way of graphing with polar coordinates. In this lesson, you will learn the definition of polar coordinates, how they can be calculated, and in what types of problems they will be useful. Practice what you have learned with example problems and a quiz after the lesson.
17. Negative Reciprocal: Definition & Examples
The negative reciprocal of a number is a very fancy word for a very simple concept. In this lesson, through definition and example, we'll learn how to find a number's negative reciprocal.
18. Solving 5 to the 4th Power
What are exponents and how do they work? This lesson explains this process using the example of raising 5 to the 4th power. We'll go over the process step by step.
19. Solving 5 to the Negative 4th Power
In this lesson, you will learn the steps of solving 5 to the negative 4th power. In doing so, you will learn the basics of exponents and negative exponents and how to solve them.
20. Elliptic vs. Hyperbolic Paraboloids: Definitions & Equations
Paraboloids are three-dimensional objects that are used in many science, engineering and architectural applications. In this lesson, we explore the elliptic paraboloid and the hyperbolic paraboloid.
21. Hyperboloids of One Sheet
It is fun to visualize the slices of a three-dimensional math object. In this lesson we use the idea of slices to understand hyperboloids of one sheet.
