Prove that any polynomial function of odd degree has at least one real root. (Hint: First show that polynomial functions are continuous on R . Then try to apply intermediate value theorem.)

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
