Domain And Range Meaning In Math

The domain of a function is all the possible input values for which the function is defined and the range is all possible output values.

Domain and range meaning in math. Domain and range the domain of a function f x is the set of all values for which the function is defined and the range of the function is the set of all values that f takes. For a relation to be a function each x value has to go to one and only one y value. The example below shows two different ways that a function can be represented.

They may also have been called the input and output of the function. In grammar school you probably called the domain the replacement set and the range the solution set. As a function table and as a set of coordinates.

The domain is the set of all possible x values which will make the function work and will output real y values. The domain and range are all real numbers because at some point the x and y values will be every real number. State the domain and range of the following relation.

The range of a function is all the possible values of the dependent variable y. If you are still confused you might consider posting your question on our message board or reading another website s lesson on domain and range to get another point of view. Let s have a look at domain and range that is given in detail here.

The line and function to the left has a domain and range of all real numbers because as the arrows indicate the graph goes on forever both negatively and positively. The set of all possible values which qualify as inputs to a function is known as the domain of the function or it can also be defined as the entire set of values possible for independent variables. If you find any duplicate x values then the different y values mean that you do not have a function.

Is the relation a function. In plain english this definition means. The domain and range of a function is all the possible values of the independent variable x for which y is defined.
