The correct statement is:
• If (x, y) is on the graph of f(x), then (x, —y) is on the graph of -f(x).
This is because the graph of -f(x) represents a reflection of the graph of f(x) across the x-axis. Therefore, if (x, y) is a point on the graph of f(x), then the corresponding point on the graph of -f(x) will be (x, -y).
