The answer to this question is C. 4, 2, or 0 positive roots and 0 negative roots

To find the possible positive and negative solutions, we need to analyze the sign changes in the coefficients of f(x) and f(-x)

Positive:

f(x) = 4x⁴ - 3x³ +2x² - x +99

+4 to -3, one sign change.

-3 to +2, one sign change.

+2 to -1, one sign change.

-1 to +99 one si...
