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 …

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

Sal is given a line segment on the coordinate plane, and he graphs the inverse of the function represented by that segment.

To find the inverse of a function, you must not only invert the operations but also the steps in which you build the original function. To start, let's list the steps to build the original g (x) function:

Now, just out of interest, let's graph the inverse function and see how it might relate to this one right over here. So if you look at it, it actually looks fairly identical.

This unit explores how functions interact through composition and inversion. You'll learn how to find and represent inverse functions, restrict domains to ensure functionality, and use compositions to verify …

The definition of an inverse function is a function that undoes another function. Say you have a function f (x) that takes in x and outputs y. f inverse of x would take in y and output x. This basically means the …

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

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 …
