Question

Is this relation a function? Give reason. In case of a function, find its domain and range:
h={(a,b)(b,c)(c,b)(d.c)}​

Answer 1

Step-by-step explanation:

Note that both relations and functions have domains and ranges. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.
