Khan Academy: Static Functions vs. Instance Methods

A video exploring whether a function is represented by a given set of points. [4:06]

The final segment in the Khan Academy's series on function inverses. Similar to the previous video, this segment does another example for finding the inverse of a quadratic function. Again the instructor explains the need for restraints...

Video evaluating combinations and compositions of functions by using a function defined by its graph. Includes link to additional practice at the top of the video. [9:14]

Video 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. Includes link for additional practice at the top...

Video evaluating combinations and compositions of functions including a piece-wise function. Focus is on understanding function notation. Includes link to additional practice at the top of the video. [9:54]

Evaluate functions for specific inputs given the graph of the function. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Determine whether a given graph represents a function. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Determine whether a table of values of a relationship represents a function. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

A review of tutorials on functions.

Shift functions horizontally and vertically, and practice the relationship between the graphical and the algebraic representations of those shifts.
