Learn what the inverse of a function is, and how to evaluate inverses of functions that are given in tables or graphs. Inverse functions, in the most general sense, are functions that "reverse" …

Not all functions have inverses. Those who do are called "invertible." Learn how we can tell whether a function is invertible or not. Inverse functions, in the most general sense, are …

Intro to inverse functions Inputs & outputs of inverse functions Graphing the inverse of a linear function Finding inverse functions: linear

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. Created by Sal …

Learn how to find the formula of the inverse function of a given function. For example, find the inverse of f (x)=3x+2.

So I'm saying that f is invertible if there exists a function, f inverse, that's a mapping from Y to X such that if I take the composition of f inverse with f, this is equal to the identity function over X.

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 …

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

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 …
