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

Actually, on a Cartesian plane, we only use the domain and range of real numbers (not rational numbers), so we do not include imaginary numbers. These are not on our normal Cartesian (x …

How do you find the domain and range of a piece-wise function using interval notation?

Domain and range from graph VA.Math: A.F.1.a, AFDA.AF.2.a VA.Math.2023: A.F.1.a, AFDA.AF.2.a Google Classroom

Learn how you can find the range of any quadratic function from its vertex form. In this article, we will learn how to find the range of quadratic functions. In other words, we will learn how to …

If you wanted to keep x minus two from being zero, x just can't be equal to two, and so typically, people would say that the domain here is all real values of x such that x does not equal two.

The domain of a function, you'll often hear it combined with domain and range. But the domain of a function is just what values can I put into a function and get a valid output.

Introducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two …

Specifically, this means that the domain of sin (x) is all real numbers, and the range is [-1,1]. See how we find the graph of y=sin (x) using the unit-circle definition of sin (x).

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 …
