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 implies that for every point \( (x,y) \) on the graph of \( f(x) \), the corresponding point \( (x,-y) \) will be on the graph of \( -f(x) \).
