| 00:0-1 | In this problem we are asked to state the domain | |
| 00:03 | and range for the following relation . 2 1 -4-0 | |
| 00:10 | , 1 And 4 -5 . Clearly we have some | |
| 00:15 | new vocabulary words to deal with domain range and relation | |
| 00:23 | . So let's start with the word relation , relation | |
| 00:28 | is simply a set of ordered pairs . Like you | |
| 00:32 | see here , the domain is the set of all | |
| 00:37 | X coordinates for those ordered pairs . So in this | |
| 00:42 | case the domain or D . Is too negative 4 | |
| 00:51 | , 0 and four . The range is the set | |
| 01:03 | of all . Why coordinates for our ordered pairs . | |
| 01:08 | So in this case our range is one to one | |
| 01:13 | and -5 . Notice that the y coordinate of one | |
| 01:19 | is repeated in two of our ordered pairs . In | |
| 01:24 | this situation we only need to mention it once in | |
| 01:27 | our range . So our range or are is 12 | |
| 01:37 | negative five . Yeah . |
