Khan Academy: Introduction to Functions: Sum of Functions

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.

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...

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

Video [6:07] showing how to solve for a function given a composition of functions and one of the functions. Also shows how the problem can be solved using the different multiple choice options.

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

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

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.

In this video students figure out the domain of a function.
