Domain And Range Of A Function Tutorial
As a function table and as a set of coordinates.
Domain and range of a function tutorial. Today we re going to talk about finding the domain and range of a function. I am often asked what is the domain and range of a function. The example below shows two different ways that a function can be represented.
The domain of a function is the collection of independent variables of x and the range is the collection of dependent variables of y. To find the domain of a function just plug the x values into the quadratic formula to get the y output. By the end of this tutorial students will be able to describe the domain and range of a function using inequalities when given a finite or infinite graph.
A table of domain and range of basic functions might be useful to answer the questions below. Such ideas are seen in high school and first ye. First the definitions of these two concepts are presented.

To find the range of a function first find the x value and y value of the vertex using the formula x b 2a. The domain of y sin x is all values of x since there are no restrictions on the values for x. The notation we also use in defining the regions of the domain and range.
In the following tutorial i continue by looking at square root and reciprocal functions. So we re going to do some examples finding the domain and range of different functions both by looking at its graph and algebraically. Students will be able to list the values of domain and range for a function given a table.
