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

Correct answer is D

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 = \(\frac{28}{x}\)`.
