The graph above is correctly represented by
-
A.
y = x2 – x – 2 -
B.
y = x2 – 3x + 2 -
C.
y = x2 – x – 1 -
D.
y = x2 + x – 2
Correct Answer: Option A
Explanation
The graph crosses the x-axis at x = -1 and x = 2
Thus, x + 1 = 0 and x – 2 = 0
x(^2) – 2x + x – 2 = 0
x(^2) – x – 2 = 0
giving y = x(^2) – x – 2
