Answer:
B
Explanation:
I would say make a quick table for each:
black:
Y I X
-2 4
-1 -2, 3.5
0 -.75, 3
1 .75, 2.5
2 2
Red:
Y I X
-2 2
-1 -1, 1.75
0 -.25, 1.5
1 .25, 1.25
2 1
The x's are almost half in the red as in the black graph.
Thinking logically you can see that the Y points stay the same so you can rule out C and D, and since the graph got smaller not bigger dividing by two will give the graph not multiplying.
