Question

What are the domain and the range of this graph?

a: the domain is x >_ 1 and the range is y >_ 1.

b: the domain is x >_ 5 and the range is y >_ 5.

c: the domain is 1 <_ x <_ 5 and the range is 1 <_ y <_ 5.

d: the domain is 0 <_ x <_ 5 and the range is 0 <_ y <_ 5

Answer 1

The endpoints of this line are (1, 5) and (5, 1). So the domain is 1 ≤ x ≤ 5, and the range is 1 ≤ y ≤ 5. The correct answer is C.
