The domain of a function is the set of all possible input values, while the range is the set of all possible output values.

The domain of a rational function consists of all the real numbers x except those for which the denominator is 0. To find these x values to be excluded from the domain of a rational function, equate the denominator to zero and solve for x.

In its simplest form the domain is all the values that go into a function, and the range is all the values that come out. Please read " What is a Function? Example: this tree grows 20 cm every year, so the height of the tree is related to its age using the function h :. Now, what comes out the Range depends on what we put in the Domain

Domain and Range of a Function

One of our main goals in mathematics is to model the real world with mathematical functions. In doing so, it is important to keep in mind the limitations of those models we create. While there is a strong relationship between the two, it would certainly be ridiculous to talk about a tree with a circumference of —3 feet, or a height of feet. When we identify limitations on the inputs and outputs of a function, we are determining the domain and range of the function. We could make an educated guess at a maximum reasonable value, or look up that the maximum circumference measured is about feet. When sending a letter through the United States Postal Service, the price depends upon the weight of the letter, 2 as shown in the table below. Determine the domain and range.

First the definitions of these two concepts are presented. Derivatives 1 15 1. The domain is the set of all possible input values. The range of a function is the set of values that the function assumes. Career Account web sites will be available during this window, but applications that use a database such as WordPress or phpBB will not work correctly. If the graph is a function, state whether it is discrete, continuous or neither.

What is the range of a function?

Notice that we can use the data to create a function of the amount each movie earned or the total ticket sales for all horror movies by year. In creating various functions using the data, we can identify different independent and dependent variables, and we can analyze the data and the functions to determine the domain and range. In this section, we will investigate methods for determining the domain and range of functions such as these. In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above.

A function is often called a map or mapping. Condition i makes sure that each element in A is related to some element of B, while condition ii makes sure that no element of A is related to more than one element of B.
