Answer:
H. {52, 72, 86, 105}
Explanation:
Given 4 ordered pairs
The question asks for domain
The domain is the x-value of each ordered pair, and usually it is listed from least to greatest (increasing order)
Take out all of the x-values of the ordered pair 52,72,86,105
Notice that above is already in increasing order, so no further action is needed.
The domain for the situation is {52, 72, 86, 105}
