Domain And Range In Inequality Interval And Set Notation
An understanding of toolkit functions can be used to find the domain and range of related functions.
Domain and range in inequality interval and set notation. D indicates that you are talking about the domain and read as negative infinity to positive infinity is another way of saying that the domain is all real numbers the range of f x x 2 in interval notation is. For many functions the domain and range can be determined from a graph. We can use interval notation to show that a value falls between two endpoints.
Notation plays an important role in mathematics. Interval values represented on a number line can be described using inequality notation set builder notation and interval notation. For f x x 2 the domain in interval notation is.
For example 3 x 2 3 2 and x ℝ 3 x 2 all mean that x is between 3 and 2 and could be either endpoint. The domain as an inequality would be x the range as an inequality would be y as a set notation. View interval notation worksheet pdf from math 101 at westlake high school.
For example if your set is composed by all the numbers smaller than 5 or between 10 and 20 or greater than 100 you write the following union of intervals. Interval values represented on a number line can be described using inequality notation set builder notation and interval notation. In the previous examples we used inequalities and lists to describe the domain of functions.
