To analyze the relationship between a point on the graph of \( f(x) \) and the graph of \( -f(x) \), let's break down the statements.
- A point \( (x, y) \) on the graph of \( f(x) \) means \( y = f(x) \).
- For \( -f(x) \), the corresponding point when we negate the function is \( (x, -y) \), which means \( y = -f(x) \).
Thus, if \( (x, y) \) is on the graph of \( f(x) \), then \( (x, -y) \) should be on the graph of \( -f(x) \).
Given this reasoning, the correct statement is:
If \( (x, y) \) is on the graph of \( f(x) \), then \( (x, -y) \) is on the graph of \( -f(x) \).
