$y=x^3-x$
RECALL: If $c$ is a zero of a function, then $x-c$ is a factor of the function. The required function has the zeros -1, 1, and 0. This means that the function has the following factors $\\x-(-1) = x+1, \\x-1, \text{ and } x$. Thus, the function is $y=(x+1)(x-1)(x) \\y=(x^2-1)(x) \\y=x^3-x$.
