Answer:
D
Step-by-step explanation:
Cubic equation: an algebraic equation of degree three and of the form
[tex]ax^3 + bx^2 + cx + d = 0[/tex], where a, b and c are the coefficients and d is the constant.
If the leading coefficient [tex]a[/tex] of a cubic equation is positive, the curve begins in quadrant III and ends in quadrant I
If the leading coefficient [tex]a[/tex] of a cubic equation is negative, the curve begins in quadrant II and ends in quadrant IV
For information
Graph A = cubic function with positive leading coefficient
Graph B = quadratic function with positive leading coefficient
Graph C = quadratic function with negative leading coefficient
Graph D = cubic function with negative leading coefficient
Therefore, if you made the leading coefficient of [tex]f(x)=x^3+3x^2[/tex] negative, it would be graph D.
