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 \((x, -y)\) will be on the graph of the function \( -f(x) \). This indicates a reflection over the x-axis.
