use the intermediate value theorem to find intervals one unit in length in which the polynomial function is guranteed to have a zero.
f(x)=x^3-3x^2+3

Question

use the intermediate value theorem to find intervals one unit in length in which the polynomial function is guranteed to have a zero. 
f(x)=x^3-3x^2+3

anonymous · Answer

make a nice guess for where this is near zero, i.e. find two successive  integers for which $f$ is negative and $f$ is positive

anonymous · Answer

-1 and 0 would work 
also 1 and 2

anonymous · Answer

$f(-1)=-1-3+3=-1$ and $f(0)=3$ so first $f$ in negative, then positive, so it must be zero some where in between

anonymous · Answer

how about h(x)=x^4-10x^2+3
