-
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 + 3×2 + 4x – 28 = 0 is by drawing the graphs of the curves
y = x2 + 3x + 4 and y = (frac{28}{x})`.
