Khan Academy: Graphing Functions: Ex 4: Graphing Radical Functions

What do you get when you cross piecewise functions with transformations?  An engaging lesson! The conclusion of a four-part series on the transformations of functions asks class members to apply transformations to piecewise...

Watch as your knowledge of quadratic functions grows parabolically. An educational video shows scholars how to graph quadratic functions. The method shown here is to create a table of values and graph the function by hand.

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

So, exactly, what does it look like? The easily usable graphing calculator allows pupils to visualize the graph of equations and inequalities. The interactive supports any algebraic graph needed for high school mathematics and then some.

Demonstrates how to graph a quadratic function by creating a table of values. This video also appears in the Algebra: Functions strand. [6:03]

Video showing how to divide radicals and then simplify the results by using the rules of exponents. [3:07]

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 add and subtract radicals by first simplifying the radicals. Video is also included in the Algebra: ck12.org strand. [7:57]

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]
