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

Functions assign a single output for each of their inputs. In this video, we see examples of various kinds of functions.

The intuition works like this: We sometimes think about functions as an input and an output. For example, we take a value, called x, and that is what we put into the function. Then the function does …

The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0.

About this unit A function is like a machine that takes an input and gives an output. Let's explore how we can graph, analyze, and create different types of functions. Unit guides are here! Power up your …

A piecewise function is a function built from pieces of different functions over different intervals. For example, we can make a piecewise function f (x) where f (x) = -9 when -9 < x ≤ -5, f (x) = 6 when -5 < …

The definition of a function is that it is a set of ordered pairs where each input (x-value) creates only one output (y-value). Based on this definition, a function does not need to be an equation. For example: h …

In this video, I want to introduce you to the idea of an exponential function and really just show you how fast these things can grow. So let's just write an example exponential function here.

A function is like a machine that takes an input and gives an output. Let's explore how we can graph, analyze, and create different types of functions.
