  • A Y = x3 and y = 3x2 + x - 28
  • B Y = x3 + 3x2 + 4x + 4 and the line y = \(\frac{28}{x}\)
  • C Y = x3 + 3x2 + 4x and y
  • D Y = x2 + 3x + 4 and y = \(\frac{28}{x}\)
  • E Y = x2 + 3x + 4 and line y = 28x
Correct Answer: Option D
Explanation:
The graphical method of solving the equation x3 + 3x2 + 4x - 28 = 0 is by drawing the graphs of the curves
y = x2 + 3x + 4 and y = \(\frac{28}{x}\)`.
