Domain and range of a graph using interval 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. Because the domain refers to the set of possible input values the domain of a graph consists of all the input values shown on the x axis the range is the set of possible output values which are shown on the y axis keep in mind that if the graph continues beyond the portion of the graph we can see the domain and. When using interval notation domain and range are written as intervals of values.
8 2 1 2 2 6 3 8 4 4 3 2 1 0 1 4 3 4 is 4 10 2 o o 3 2 o 2 name the domain and range of each relation using interval notation. Y 0 remember to focus on bottom to top of the graph for range of a continuous graph. Interval values represented on a number line can be described using inequality notation set builder notation and interval notation.
Graph the function g x 2 x 1 and give its domain and range using interval notation. We write the domain in interval notation as x 0. 10 2 s 8 10 123 5.
Big idea to have a deeper understanding of interval notation from inequalities and how the square bracket includes the number and the parentheses does not include it. For each number line write the given set of numbers in interval notation. Find domain and range using interval notation 17017270.
Here 1 2 is greater than or equal to x so this is your greatest value so the interval notation for the this problem is negative infinite symbol 1 2 13 15 if it says y a number that is your range then your domain would be everything. Notice that this graph has one endpoint at 0 0 and an arrow therefore this graph covers all y values that are greater than or. Another way to identify the domain and range of functions is by using graphs.
Swbat write the domain and range of a graph using interval notation by comparing it to set builder notation.
