The function f has a domain of (2,4,6,8) and a range of 1,5,9. Could f be represented by (2,1)(4,5)(6,9),(8,1)? Justify your answer

## 1 Expert Answer

Domain refers to the possible x-values, while range refers to the possible y-values.

If we look at the coordinates given for f:

- (2,1)
- 2 is in the domain (2, 4, 6, 8)
- 1 is in the range (1, 5, 9)
- (4,5)
- 4 is in the domain (2, 4, 6, 8)
- 5 is in the range (1, 5, 9)
- (6,9)
- 6 is in the domain (2, 4, 6, 8)
- 9 is in the range (1, 5, 9)
- (8,1)
- 8 is in the domain (2, 4, 6, 8)
- 1 is in the range (1, 5, 9)

Therefore, f could be represented by those coordinates.

If, on the other hand, the function included the point (2,4), then it couldn't be f because although 2 is in the domain, 4 is not included in the range of f.
