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.

What are rational functions? How do we plot them? What is their domain and range? Let's find out. We break down the definition of the function given in set-builder form and plot the graph …

Yes, a function can have multiple inputs. We can graph in the coordinate plane when we have 1 input to 1 output. If we have a function with 2 inputs to create 1 output, we can graph in a 3 …

Learn to recognize functions and graphical relations with Khan Academy's interactive lessons and resources.

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 …

When distances, prices, or any other quantity in our world changes at a constant rate, we can use linear functions to model them. Let's learn how different representations, including graphs and …
