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 if you have a point \((x, y)\) on the graph of the function \( f(x) \), then the point will reflect across the x-axis to give you the point \((x, -y)\) on the graph of \( -f(x) \).
