1.  at year

0=100

8=731

  9 = 803

  10=858

11=901

15 =978

20=996

So 'a' is correct   and  'b' is correct and d is correct bu c is not

 

2.   this function has values for all x as long as   x-3 is not NEGATIVE

        so domain = 3 to infinity   (includes 3)

     the corresponding range for these values of x goes from 0 to infinity

         so the second choice is good
