#1**+1 **

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
