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.

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

In this unit, we learn about functions, which are mathematical entities that assign unique outputs to given inputs. We'll evaluate, graph, analyze, and create various types of functions.

Types of Functions Learn Surjective (onto) and injective (one-to-one) functions Identity and constant functions

Equations and functions are not the same thing, but they can be related in several ways. Watch Jesse Roe and Sal talk about the difference between equations and functions.

There's another powerful thing we can do with functions - we can use them to take in some values, compute them, and return a new value. Think about all the things you can do with a calculator - add …

The range of a function is the set of all possible outputs the function can produce. Some functions (like linear functions) can have a range of all real numbers, but lots of functions have a more limited set of …

If you're talking about evaluating functions, then it works the exact same way as evaluating algebraic expressions. Replace all instances of the variable with its substituted value, and simplify using the …
