Question 885104: 9) Give the domain of h = {(–1, 4), (2, 7), (3, 7)} and tell if “h” is a function.
a.) {4, 7}, h is a function
b.) {4, 7}, h is not a function
c.) {–1, 2, 3}, h is not a function
d.) {–1, 2, 3}, h is a function

The domain is the set of allowed x values. So it's {–1, 2, 3}

This is a function because each x value maps to exactly one y value (you don't have some x value mapping to more than one y value)

So the answer is d.) {–1, 2, 3}, h is a function
