Khan Academy: Shell Method: Part 2 of Shell Method With 2 Functions of Y

Dive into an activity that may cause a little reflection! Building from the first lesson in the series of two, learners explore transformation using unfamiliar functions. The key takeaway is that applying transformations to any function...

This video continues to look at evaluating functions by looking at examples of evaluating basic composite functions.

Young mathematicians will appreciate Sal's careful - yet efficient - methods for solving these typical SAT problems. He takes care to explain problems 8-12, but gets cut off in the middle of problem 12 (to be continues in the next video).

Helping students realize the common missteps in solving the average SAT problem, Sal creates a lens through which students can clearly see the correct and incorrect approach to each type of problem. He points out what a student might...

Sal continues looking at function inverses in this video by showing two examples. In each example, he finds the inverse and shows the graph of both functions. His examples are with linear functions, but his first example shows a function...

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]

Find the volume using the washer method.

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 defining the vertex and axis of symmetry for a parabola. Vertex is found for a specific function by completing the square to change the equation from standard form to vertex form and then reasoning through the equation. Axis of...
