If y = 6x - 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs {(0, 3), (1, -9), (2,-15) (0, -3), (2, 15), (4,21)} (0, -3). (2,9),(4,21)} {(0.3),(-2, 15), (4, 21)}

Answer : (0, -3) ; (4,21) and (2,9)

Step-by-step explanation:

y = 6x- 3

y =0*x-3 = -3           (0,3) is not a possible set y = 1*6-3 = 3            (1,-9)  is not a possible set y = 6*2-3 = 9              (2,-15) is not a posiible set (0.-3) is a possible set as verified in the first one (2,15) is not a possible set since the output of 2 is 9 y = 4*6-3 = 21            so (4,21) is possible set (2,9) is a possible set as verified in the third one

It will might be false
