Question

He polynomial p(x) = x5 − 9x4 13x3 57x2 − 86x − 120 has a total of zeroes. it can have a maximum of positive real roots and a maximum of negative real roots

Answer 1

He polynomial p(x) = x5 − 9x4 13x3 57x2 − 86x − 120 has a total of zeroes.

The domain of the polynomial is all real number

Its range is also all real number

The real root of the polynomial is x = 10.7751

The local maximum is at x = - 0.7945

Its local minimum is at x = 8.4675
