1. What Is Domain and Range in a Function?
The domain and range are the possible outputs and inputs of a function. In this lesson, learn about what might restrict the domain and how to figure out the domain and range from a graph.
2. What is Function Notation: Definition & Examples
After completing this lesson, you will be able to recognize function notation. You will also be able to evaluate functions correctly using function notation.
3. What is a Function? - Applying the Vertical Line Test
Equations come in all shapes and sizes. Trying to determine which equations are functions can be difficult. You can apply the vertical line test to a graph to quickly tell whether or not it is a function.
4. Representing Functions as Ordered Pairs
Functions are a mathematical concept that show up everywhere in the world around us. This lesson will use definitions and examples to show how to use ordered pairs to represent functions.
