Learn what the inverse of a function is, and how to evaluate inverses of functions that are given in tables or graphs.

This right over here is our understanding inverses of functions exercise on Khan Academy. It's a good exercise to make sure you understand inverses of functions.

Read values of an inverse function from a graph or a table of the original function.

Learn how to find the inverse of a function and how to graph it in this video. The inverse function swaps the x and y values of the original function, and the graph of this inverse function is a reflection of the …

This topic covers: - Evaluating functions - Domain & range of functions - Graphical features of functions - Average rate of change of functions - Function combination and composition - Function …

Sal explains what inverse functions are. Then he explains how to algebraically find the inverse of a function and looks at the graphical relationship between inverse functions.

Plotting the graphs of inverse trigonometric functions can seem unintuitive at first. But don’t worry! All you need is the graph of the sine function and an inquisitive mind, and together, we'll successfully …

We can compose functions by making the output of one function the input of another one. This simple-yet-rich idea opens up a world of fascinating applications. Inverse functions undo each other when …

If a point (a, b) is on the graph of a function, then (b, a) is on the graph of its inverse. You can check that y=x is the perpendicular bisector of the line between these points, so these points are a reflection …
