Question

suppose that the relation T is defined as follows.
T={(-4,-6), (-4,7), (0,9), (9,-1)}

give the domain and range of T.

write your answers using set notation.

domain=

range=

Answer 1

The domain of T is the set of all x-coordinates in the relation T.

So the domain of T is {-4, 0, 9}.

The range of T is the set of all y-coordinates in the relation T.

So the range of T is {-6, 7, 9, -1}.
