Inverse functions, in the most general sense, are functions that "reverse" each other. For example, if f takes a to b , then the inverse, f 1 , must take b to a .

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" …

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.

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 …

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 …

Some cubic functions such as the parent function (y=x^3) or with just a cube and constant (y=x^3 - 27) would have inverses that are functions. By starting out with a function, you know it …

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.

We've got the function f of x is equal to x plus 2 squared plus 1, and we've constrained our domain that x has to be greater than or equal to negative 2. That's where we've defined our …

Practice finding the formula of the inverse function of a given linear function.
