Domain And Range Interval Notation Notes

When using interval notation domain and range are written as intervals of values.

Domain and range interval notation notes. The interval for both will be all real numbers or negative infinity to positive infinity. The set of even numbers from 1 to 10. In interval notation there are five basic symbols to be familiar with.

We write the range in interval notation as y 0. Determine the domain and range for the graph below. But we can also build a set by describing what is in it.

A n 40 b z 2 or z 5 c domain. Interval values represented on a number line can be described using inequality notation set builder notation and interval notation. An understanding of toolkit functions can be used to find the domain and range of related functions.

Open parentheses closed parentheses infinity imagine an 8 sideways negative infinity an 8 sideways with a negative sign in front of it and union a symbol similar to an elongated u. In the previous examples we used inequalities and lists to describe the domain of functions. 5 7 11 is a set.

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. Express each set of numbers in set notation. Notes in class practice set and interval notation set notation a set is a collection of things usually numbers.

Interval notation is a method used to write the domain and range of a function. For many functions the domain and range can be determined from a graph. For the domain and the range we approximate the smallest and largest values since they do not fall exactly on the grid lines.
