Define the relation T on ℝ+ by
T = {(x, y):y=7/2X-5}
(i) State the domain and range of T.
(ii) Is T a function? State your reason.
i)for domain: 2x-5>0 -> x>5/2 (domain of T)
Range: o<y<+infinity
ii)Yes, T is a function because each value in domain is only maped to a single value in domain.
this is my ans, can i check if i am right or wrong?
