To describe the relationship between a point on the graph of \( f(x) \) and a point on the graph of \( f(-x) \), let's denote a point on the graph of \( f(x) \) as \( (x, y) \), where \( y = f(x) \).
When we consider \( f(-x) \), we find that:
- The input is \(-x\).
- The value of the function at this point would be \( f(-x) \).
The relationship that describes a point on the graph of \( f(-x) \) corresponding to \( (x, y) \) is:
If \( (x, y) \) is on the graph of \( f(x) \), then \( (-x, y) \) is on the graph of \( f(-x) \).
Therefore, the correct option is:
\((-x, y)\)
