Domain And Range Using Set Notation
Use notations to specify domain and range in the previous examples we used inequalities and lists to describe the domain of functions.
Domain and range using set notation. Set notation is used to indicate the domain and range as a set of numbers. Having a clear understanding of what the inequalities symbols mean will help my students to achieve the goal of this lesson. I use it to access their prior knowledge of inequalities or refresh their memory if necessary.
Though not as compact as interval notation it is a way that mathematicians use to convey two important pieces of information. Y y 0 r indicates range. Therefore this statement can be read as the range is the set of all y such that y is greater than or equal to zero.
When using set notation inequality symbols such as are used to describe the domain and range. We can also use inequalities or other statements that might define sets of values or data to describe the behavior of the variable in set builder notation. The range of f x x 2 in set notation is.
