Hi everyone. I've been having problem with the one function h(x)=(x^3-1)/(x^3-x) I need to find all points of discontinuity. Thx for any help

Thx for any help Did you try to factor it? $\displaystyle h(x)=\frac{x^3-1}{x^3-x}=\frac{x^3-1}{x(x^2-1)}=\frac{(x-1)(x^2+x+1)}{x(x+1)(x-1)}$ Can you take it from here? It should be no problem now. --Chris
