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:

Or another way to write it is we could say that f inverse of y is equal to negative y plus 4. So this is the inverse function right here, and we've written it as a function of y, but we can just rename …

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

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.

You'll learn how to find and represent inverse functions, restrict domains to ensure functionality, and use compositions to verify inverses. Unit guides are here!

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 …

About this unit A function is like a machine that takes an input and gives an output. Let's explore how we can graph, analyze, and create different types of functions. Unit guides are here! …

Since we know all of our side lengths now, we just need to use the inverse functions to calculate our angles. Let's find out angle O: angle O is adjacent to line OE, opposite of line ZE, and our …

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 …
