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 corresponding point on the graph of \( -f(x) \) would be \( (x, -y) \), reflecting the point across the x-axis.
