Chapter 8 - Section 8.4 - Interval Notation, Finding Domains and Ranges from Graphs, and Graphing Piecewise-Defined Functions - Exercise Set - Page 604: 2


Interval Notation: (5, infinity) Number Line: Open circle on 5, the entire right side of 5 on the number line is shaded

Work Step by Step

Because x > 5, 5 is not included in the number line. Therefore, the solution will include all values that are to the right of 5 on the number line, excluding 5. The interval notation uses open brackets because 5 and infinity are not included.
