Identify the total number of roots, the possible number of
positive real roots, and the possible number of negative real roots for
the following function:
f(x) = x5 + 3x4 - 6x³ + 8x² - 2x - 1

a. Real Roots = 5, # of Positive Roots = 3 or 1, # of Negative
Roots 2 or 0
b. Real Roots = 5, # of Positive Roots = 3, # of Negative Roots = 2
c. Real Roots = 6, # of Positive Roots = 3 or 1, # of Negative
Roots=2 or 0
d. Real Roots = 6, # of Positive Roots = 3, # of Negative Roots = 2
