The graph above is correctly represented by
-
y = x2 - x - 2
- y = x2 - 3x + 2
- y = x2 - x - 1
- y = x2 + x - 2
The correct answer is: 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
