Read values of an inverse function from a graph or a table of the original function.

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

If you want a hard concrete example, if you every plan to drive a car, turning the steering wheel is a function that outputs how much the tires of the car turn.

The next couple of videos we'll do a bunch of examples so you really understand how to solve these and are able to do the exercises on our application for this.

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 reflection of the …

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" …

Sal explains what it means for quantities to vary directly or inversely, and gives many examples of both types of variation.
