Find the least integral upper bound of the zeros of the function f(x)=x^3-x^2+1

So by the rational root theorem, 1 and -1 might be roots.

by using synthetic division, i get the following values:

for f(-1)=-1

f(0)=1

f(1)=1

f(2)=5

and there is changes in the signs of the remainder/quotient for -1 and 0, but no changes for 1 and 2.

So would 1 be the upper bound, or 2?

Thanks for the help.

the only real zero is negative, so I guess would 0 be the upper bound? maybe? lol
