Answer:
   x g(x)
   1 −10
   2 −12
   3 −14
Step-by-step explanation:
Substitute the values and do the arithmetic.
Table values for x are 1, 2, 3. We only need to find g(1) to determine which table is the correct choice.
   f(1) = 1 +4 = 5 . . . . . . . . . put 1 where x is and do the arithmetic
  g(1) = -2·f(1) = -2·5 = -10 . . . . . matches the 3rd choice
