Answer:
1) True
2) False
3) True
4) False
5) False
Explanations:
Domains are indepedent variables for which a function exists while the range are dependent variables for which a function exist.
Foa a given coordinates (x, y), all the sets of first coordinates are the domain while all the sets of second coordinates are the range;
All functions are also known as relations but not all given relations are function.
Based on the explanations above, then;
1) A relation is a set of ordered pairs is TRUE
2) The set of all the first coordinates is called is range is FALSE
3) All functions are relations is TRUE
4) The set of all the second coordinates is called is domain is FALSE
5) All relations are function is FALSE
