To analyze the relationship between any point on the graph of \( f(x) \) and \( -f(-x) \), let's start with the definition of these functions.

  1. If \( (x,y) \) is a point on the graph of \( f(x) \), it means that \( y = f(x) \).
  2. To find the corresponding point for \( -f(-x) \), we need to evaluate \( -f(-x) \):
    • If we substitute \( -x \) into \( f(x) \), we get \( f(-x) \).
    • Therefore, \( -f(-x) \) would give us \( -f(-x) \).
  3. The point that corresponds to \( (x,y) \) under the transformation leading to \( -f(-x) \) would specifically be \( (-x, -y) \) because:
    • We take \( x \) and transform it to \( -x \) and take \( y \) (which is \( f(x) \)) and transform it to \( -y \).

Thus, we can conclude that: If \( (x,y) \) is on the graph of \( f(x) \), then \( (-x, -y) \) is on the graph of \( -f(-x) \).

The correct choice from the response options provided is: If (x,y) is on the graph of f(x), then (−x,−y) is on the graph of −f(−x).
