The positive integer x is a multiple of 9 and also a
multiple of 12. the smallest possible value of x is
(a) 3
(b) 12
(c) 21
(d) 36
(e) 72

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
