Question

Which function represents the data in the table

X: 3,6,10,15
Y: 2.5,4,6,8.5


A. F(x)=2x+1
B. F(x)=x/2-1
C. F(x)=2x-1
D. F(c)=x/2+1

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!!
