First the definitions of these two concepts are presented. Derivatives 1 15 1.
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 In fact the Domain is an essential part of the 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. We also need to consider what is mathematically permitted.
