Which of the relations has a domain of {-5, 0, 5}? {(-5, 0), (0, 5), (1, 0)} {(-5, 5), (0, 5), (5,5)} {(0, -5), (0, 0), (0, 5)}?

The relation which has a domain of {-5, 0, 5} is:

               {(-5, 5), (0, 5), (5,5)}

Domain--

A domain is the set of all the possible x-values i.e. it is the first element of a ordered pair i.e. (x,y)

Range--

It is the set of all the y-values i.e. it is the second element in the set of the ordered pair i.e. (x,y)

a)

{(-5, 0), (0, 5), (1, 0)}

The domain of this relation is: {-5,0,1}

Range is: {0,5}

b)
