The domain of the following relation: r: {(-4-9) } is

{-4, 8, 5, 1, 5}

Step-by-step explanation:

In a set of ordered pairs, the domain is the set of the first number in every pair.

If the set of ordered pairs is {(-4,8), (8,10), (5,4), (1,6), (5,-9)},

                      the domain is {  -4,     8,        5,     1,      5}

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
