Classify the polynomial 3x^5 by degree A: cubicB:quadratic C:quinticD:quartic
Accepted Solution
A:
The answer is: [C]: "quintic" . ______________________________________________________ Note: The prefix "quint-" is ONE of the prefixes (other than "pent-") that means "5" ; and considering: "3x⁵ " ; we consider the "largest exponent value corresponding to a variable"— which, in the question, is "5" — as the "degree of the polynomial" . ______________________________________________________ Consider: "Choice: [A]: "cubic". This answer is incorrect. This choice would be correct IF the polynomial was: " 3x³ " . ___________________________________________________________ Consider: "Choice: [B]: "quadratic" ; is incorrect. This would refer to an equation, in "quadratic form" ; that is: " ax² + bx + c = 0 ; { b[tex] \neq [/tex]0 } . " . ___________________________________________________________ Consider: "Choice: [D]: "quartic" ; is incorrect. This would refer to: " 3x⁴ " . ___________________________________________________________
