The function \( f \) is defined on the real numbers and satisfies the following conditions: for any real number \( x \), \( f(2+x) = f(2-x) \) and \( f(7+x) = f(7-x) \).

If \( x = 0 \) is a root of \( f(x) = 0 \), then how many roots does \( f(x) = 0 \) have in the interval \( -1000 \leq x \leq 1000 \)?
