Describe Domain and Range of a Function
We can write the domain and range in interval notation which uses values within brackets to describe a set of numbers. The set X is called the domain of the function and the set Y is called the codomain of the function. Activity Exploring Domain And Range Algebra 1 Ti Math Nspired Algebra Algebra I Algebra 1 For example the position of a planet is a function of time. . In mathematics a function from a set X to a set Y assigns to each element of X exactly one element of Y. We can visualize the domain as a holding area that contains raw materials for a function machine and the range as another holding area for the machines products Figure 332.
