The graphical method of solving the equation x³ + 3x² + 4x - 28 = 0 is by drawing the graphs of the curves

• 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
