Finding the domain and the range of a function that is given graphically. Created by Sal Khan.

We break down the definition of the function given in set-builder form and plot the graph by connecting points on the cartesian plane. Domain and Range is calculated through visually observing the graph.

Let's take a look at an example where plotting a graph can help us figure out the domain and range of a function. Even if that function is not a polynomial. We break down the definition of the function given …

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 …
