The graph above is represented by
Attached Figure / Diagram
A
y = x3 - 3x - 2
B
y = x3 + 2x2 - x - 2
C
y = x3 - 4x2 + 5x - 2
D
y = x3 - 4x + 2
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
x = -2, x = -1 and x = 1
then the factors; x+2, x+1 and x-1
Product of the factors; (x+2)(x+1)(x-1)
= y = (x + 2)(x2 - x + x - 1)
= y = (x+2)(x2-1)
x3 - x + 2x2 - 2 = y
x3 + 2x2 - x - 2 = y
