Please help super confused!!!

Which points are the best approximation of the relative maximum and minimum of the function?

f(x)=x^3+3x^2-9x-8

a. Relative max is at (3,-13), relative min is at (-3,-19).
b. Relative max is at (-3,19), relative min is at (1,-13).
c. Relative max is at (3,-13), relative min is at (3,-19).
d. Relative max is at (-3,-19), relative min is at (-1,-13).
