B) $x = 7$
C) $x = - 2,401 , x = 2,401$
D) $x = - 7$

To find the zeros of the function $f(x) = x^2 - 49$, set $f(x) = 0$ and solve for $x$. This gives $x^2 - 49 = 0$, which simplifies to $x^2 = 49$. Taking the square root of both sides gives $x = \pm\sqrt{49}$, which simplifies to $x = \pm7$. Therefore, the x-intercepts are $x = -7$ and $x = 7$.
