Answer:

6x^2 -9

Explanation:

1. From the table, you know that when x = 0, y = -9, this means that the initial value is -9. This means that the last option is not correct

*** y values -> output

2. Plug in a x - value from the table to figure out the right rule:

x = 2

First option: 6x - 9 -> 6*2 - 9 = 12-9 = 7

in the table, the output for x =2 is 15 so the first option is not correct

Second option: 6x^2 - 9 -> 6*(2^2) - 9 = 6*4 - 9 = 24 - 9 = 15

in the table, the output for x =2 is 15 so the second option is correct
