According to the Fundamental Theorem of Algebra, which polynomial function has exactly 8 roots? f (x) = (3 x squared minus 4 x minus 5) (2 x Superscript 6 Baseline minus 5) f (x) = (3 x Superscript 4 Baseline + 2 x) Superscript 4 f (x) = (4 x squared minus 7) cubed f (x) = (6 x Superscript 8 Baseline minus 4 x Superscript 5 minus 1) (3 x squared minus 4)
