Find the x-intercepts (if any) for the graph of the quadratic function.
-$$f ( x ) = x ^ { 2 } - 1$$
A) No x-intercepts
B) $( - 1,0 )$
C) $( - 1,0 )$ and $( 1,0 )$
D) $( 1,0 )$

To find the x-intercepts, set $f(x) = 0$ and solve for $x$. Thus, $x^2 - 1 = 0$ leads to $x^2 = 1$, giving $x = \pm 1$. Therefore, the x-intercepts are $(-1, 0)$ and $(1, 0)$.
