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

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 …

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 …

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

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

And in the next video or the video after that, we'll solve an example where you want to take the negative square root. So we're going to take theundefined positive square root, or just the …

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 …

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 …

Review your knowledge of the inverse trigonometric functions, arcsin (x), arccos (x), & arctan (x).
