Needing an answer ASAP! According to the Fundamental Theorem of Algebra, which polynomial function has exactly 6 roots? f (x) = 5 x Superscript 4 Baseline + 10 x squared + 2 f (x) = 5 x Superscript 5 Baseline + 3 x Superscript 4 Baseline + 12 x cubed + 7 x squared minus 2 x + 15 f (x) = 6 x Superscript 5 Baseline + x cubed minus 4 x squared + x minus 5 f (x) = 7 x Superscript 6 Baseline + 3 x cubed + 12
