Find the x-intercepts (if any) for the graph of the quadratic function.
-$$f ( x ) = x ^ { 2 } - 4$$
A) $( - 4,0 )$
B) $( 2,0 )$
C) $( - 2,0 )$ and $( 2,0 )$
D) No x-intercepts

To find the x-intercepts, set $f(x) = 0$ and solve for $x$. Thus, $x^2 - 4 = 0$ leads to $x^2 = 4$, and solving for $x$ gives $x = \pm 2$, which corresponds to the points $(-2,0)$ and $(2,0)$.
