Learn how to find the domain and range of linear and quadratic functions. Understand the meaning of domain and range and how to calculate them algebraically and graphically with examples.
Determining the Domain and Range Modeled by a Linear Function. To determine the domain of a given situation, identify all possible x -values, or values of the independent variable. To determine the range of a given situation, identify all possible y -values, or values of the dependent variable. Example 1.
The domain and range of a linear function f(x) = ax + b is R (all real numbers) whereas the range of a constant function f(x) = b is {b}. These linear functions are useful to represent the objective function in linear programming.
The domain and range of a function are the components of a function. The domain is the set of all the input values of a function and the range is the possible output given by the function. Domain→ Function →Range.
Finding the Domain of a Function Defined by an Equation. 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.
