What's the domain of the relation? {(15, 65), (21, 70), (18, 73), (16,62)}

Solution:

we have been asked to find the domain of the given relation.

The given relation is

{(15, 65), (21, 70), (18, 73), (16,62)}

As we know that in the given relation the x-ccordinate represents the domain and the y-coordinates represents the range.

Hence for the given relation {(15, 65), (21, 70), (18, 73), (16,62)}

Domain={15,21,18,16}.

Range={65,70,73,62}

a.)the line for function b is steeper
