Domain and range of a function in interval notation. Write the domain of the graph of the function shown below in interval notation. The procedure for doing interval notation include. Write the numbers separated by a comma in ascending order.
Interval notation is a method used to write the domain and range of a function. A continuous graph with two endpoints. The open circles at x 4 x 2 and x 2 indicates that these values are not included in the domain.
Hence the domain in interval notation is given by the set 1 u 1 matched problem 1 find the domain of function f defined by answers to matched problems 1 2 3 and 4. In interval notation there are five basic symbols to be familiar with. Since the range and domain of a function are usually expressed in interval notation it s important therefore to discuss the concept of interval notation.
We use interval notation to help us describe the domain and range for graphs that represent continuous situations. 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. Hence the domain in interval notation is written as.
Two endpoints graph covers all. Please review the following information to help you describe the domain and range for three different types of continuous graphs. Given x x 6 the domain of a function in set builder notation which of the following rewrites it in interval notation.
Solution to example 6 the graph starts at values of x 8 and ends at values of x 2. For the domain and the range we approximate the smallest and largest values since they do not fall exactly on the grid lines. In interval notation the domain is 1973 2008 and the range is about 180 2010.
