Sal continues showing examples of finding the inverse of the function. Here, he shows a subtle but essential technique of taking the negative square root of each side of the equation when solving for the inverse because of the...

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...

Sal shows an example of finding the inverse of the parabola with a restricted domain. He alludes to a reason behind the restricted domain but leaves the listener to determine it.

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...

An instructional video explaining the concept of function inverses. A linear function is given and a diagram is drawn to show the mapping of some elements of the domain to the corresponding elements in the range. The inverse of the...

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...
