Khan Academy: Introduction to Functions: Functions (Part 4)

In this functions learning exercise, students solve 70 short answer questions. Students find domain of functions and evaluate them for a given value. Students determine if a mapping diagram represents a function.

Starting from a brief look at functions and the mapping of domains to ranges, Sal starts with an intuitive sense of what a function inverse is. Using an example, he then shows how to find the inverse of a function and how the graph of...

Let the video function as a catalyst to study functions. Young mathematicians watch a short video to continue learning about functions. They watch as the narrator completes function tables by evaluating functions for specific values,...

This interactive website provides a variety of lesson plans according to which standards you are applying and which textbook you use. Introduce functions to your class by having them construct single operation machines and create...

Video [9:53] evaluating combinations and compositions of functions including a piece-wise function. Focus is on understanding function notation.

Functions are investigated in this video tutorial.[9:33] Students learn about the algebra concept through detailed examples.

Video finding the product of a linear function and a cubic function by using the distributive property.

Video finding the sum of two quadratic functions.

This video demonstrates how to take a word problem and write a linear function that represents the problem.

Video finding the quotient of two quadratic functions and then simplifying by factoring.
