Step-by-step explanation:
Inupt values for y and evaluate to get y values
(x,y)
if x=0
y=3(0)-1
y=0-1
y=-1
(0,-1)
if x=1
y=3(1)-1
y=3-1
y=2
(1,2)
if x=2
y=3(2)-1
y=6-1
y=5
(2,5)
if x=3
y=3(3)-1
y=9-1
y=8
(3,8)
look for the points
(0,-1) (1,2) (2,5) (3,8)
B
There should not be a -5 outside of the parenthesis in the second line
Answer:
