(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Consider the following mathematical items. For each item,(1) indicate whether it has a natural interpretation as a function, a correspondence, or neither. If the item is a function or a correspondence, the indicate (2) its domain and range and (3) whether it is (a) real, (b) single-valued and (c) univariate.

If the item is not a function, or is not real, single-valued or univariate, then justify your answer briefly.

3. The attempt at a solution

1. (1,1), (2,2), (3,3) is a function. Domain (1,2, 3), Range (1,2, 3)Single-valued?

2. (1,1), (2,2), (1,3) is NOT a fuction. Domain (1,2), Range (1,2, 3)Single-valued

3. (1,1), (2,1), (3,1) is a function. Domain (1,2, 3), Range (1)Single-valued

4. (1,1), (2,(3,1)), (3,1) is a function. Domain (1,2, 3), Range (1, 3)-is it correct?Univariate

5) ((1,1),2), ((2,1),3), ((2,1),4) is NOT a function. Domain (?), Range (2,3,4)Univariate

Any mistakes?
