  • A Y = \(x^2 - 5x - 6\)
  • B Y = \(x^2 + 5x - 6\)
  • C Y = \(x^2 + x - 6\)
  • D Y = \(x^2 - x - 6\)
Correct Answer: Option n
Explanation:
Since the curve cuts the x-axis at x = -2 and x = 3,
(x + 2)(x - 3) = 0
\(x^2 - 3x + 2x - 6\) = 0
\(x^2 - x - 6\) = 0
Hence, the equation of the curve is
y = \(x^2 - x - 6\)
