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 .

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.

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 functions that "reverse" …

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 …

Sal explains that if f (a)=b, then f ⁻¹ (b)=a, or in other words, the inverse function of f outputs a when its input is b.

But the general idea, you literally just-- a function is originally expressed, is solved for y in terms of x. You just do some algebra. Solve for x in terms of y, and that's essentially your inverse function as a …

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. Inverse functions, in the most general sense, are functions that "reverse" each other. For …

The inverse of a function ƒ is a function that maps every output in ƒ's range to its corresponding input in ƒ's domain. We can find an expression for the inverse of ƒ by solving the equation 𝘹=ƒ (𝘺) for the …

Let's explore the intriguing relationship between a function and its inverse, focusing on the function f (x)=½x³+3x-4. We delve into the derivative of the inverse of f, applying the chain rule and the power …
