The correct statement to describe the relationship between any point on \( f(x) \) and \( -f(x) \) is:
If \((x,y)\) is on the graph of \( f(x) \), then \((x,-y)\) is on the graph of \( -f(x) \).
This means that for every point \((x,y)\) on the graph of the function \( f(x) \), the corresponding point on the graph of \( -f(x) \) will have the same \( x \)-coordinate and the \( y \)-coordinate will be negated.
