Question

PLEASE HELP :(

The value of 5 is an upper bound for the zeros of the function shown below .

F(x)=x^4+x^3-11x^2-9x+18

A)True
B)False

Answer 1

perhaps you meant 5 is an upper bound for the NUMBER of zeros, then true

since f(x) is a 4th degree polynomial, it has at most 4 solutions.

Answer 2

so it would be false

Answer 3

it is true
