D is inversely proportional to (w + 1)?.
d= 3.2 when w=4.
Find d when w= 7.

  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.

you can't solve x because it is 2 linear equation and you only have one equation
