- [Instructor] In this video, we're gonna do a few examples finding domains of functions. So let's say that we have the function f of x is equal to x plus five over x minus two.

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

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.

Determine the domain of a function according to the algebraic limitations of that function.

Many examples of determining the domains of functions according to mathematical limitations.

The domain of a function is the set of all acceptable input values that can be used for that function. An interval is a contiguous set of numbers (usually real numbers) and is often shown …

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 …

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

Use information about a situation to figure out the domain of the function which models it.

The domain is the possible numbers n can be that would accurately describe the sequence. For example, the difference between whether n>=1 or n>=0 depends on whether the range …
