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

{(0,-3),(2,9),(4,21)}

Explanation:

This is because

-3 = 6*0-3

9 = 6*2-3

21 = 6*4-3
