  (d)  -90

Step-by-step explanation:

The function can be simplified to ...

  f(x) = -9(x +1)

This means any integer x will produce a y-value that is a multiple of 9. Among the answer choices, those are 90 and -90. We can try these to see if either of the x-values are in the table.

  90 = -9(x +1)

  -10 = x +1

  -11 = x . . . . . not in the table

__

  -90 = -9(x +1)

  10 = x +1

  9 = x . . . . . . . the first row of the table

The value -90 would be correctly found in the table.
