Question

Which function represents the data in the table

Answer 1

It would be d because if you plug in f(6)=(3/2)+1 it would be f(6)=3+1 or f(6)=4.  This works for any other of the coordinates.

Answer 2

The answer is D, because

3/2=1.5+1= 2.5
6/2=3+1=4
10/2=5+1=6
15/2=7.7+1=8.5 

D is your answer 
hope I helped!!
