Respuesta :

Remember that

For a set of ordered pairs, the first elements of each ordered pair represent the domain of the function and the second element of each ordered pair represent the range of the function

In this problem, we have the data set

{(4,6), (0,3), (2, 2), (7,-1)}

so

The domain is

{4,0,2,7}

therefore

3 and -4 are not elements of the domain

The answer is options A and C
