This question asks us to find the function that is satisfied by all four ordered pairs. Here, it is probably easiest to work by process of elimination, and cross off those choices that aren't satisfied by at least one of the ordered pairs. Let's consider the first ordered pair, (2, 1), and see which functions give an output of 1 for an input of 2:
(A) f(2) = 3(2)2 - 2 = 3(4) - 2 = 12 - 2 = 10 (No—eliminate.)
(B) f(2) = 3(2)2 - 4 = 3(4) - 4 = 12 - 4 = 8 (No—eliminate.)
(C) f(2) = 2(2)2 - 7 = 2(4) - 7 = 8 - 7 = 1 (Yes—don't eliminate.)
(D) f(2) = 2(2)2 = 2(4) = 8 (No—eliminate.)
So, it turns out we only have to test one ordered pair to get the right answer.
(A) f(2) = 3(2)2 - 2 = 3(4) - 2 = 12 - 2 = 10 (No—eliminate.)
(B) f(2) = 3(2)2 - 4 = 3(4) - 4 = 12 - 4 = 8 (No—eliminate.)
(C) f(2) = 2(2)2 - 7 = 2(4) - 7 = 8 - 7 = 1 (Yes—don't eliminate.)
(D) f(2) = 2(2)2 = 2(4) = 8 (No—eliminate.)
So, it turns out we only have to test one ordered pair to get the right answer.
