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.
