Question

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 1

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

Explanation:

Answer 2

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

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
