To find the true relationship between any point on \( f(x) \) and \( -f(-x) \), we need to analyze the transformations that occur.

  1. If \( (x, y) \) is on the graph of \( f(x) \), then \( y = f(x) \).
  2. To get the point for \( -f(-x) \):
    • First, replace \( x \) with \( -x \), resulting in \( f(-x) \).
    • Then negate this value, leading to \( -f(-x) \), meaning the output becomes \( -f(-x) \).

Now, let’s define what that means for \( y \):

  • If \( (x, y) \) is on the graph of \( f(x) \), then:
    • \( y = f(x) \),
    • The corresponding point for \( -f(-x) \) would be \( (-x, -y) \) because when \( x \) changes to \( -x \), the function value becomes \( f(-x) \) and negating that gives \( -f(-x) \).

Thus, if \( (x, y) \) is on the graph of \( f(x) \), then the point \( (-x, -y) \) will indeed be on the graph of \( -f(-x) \).

The correct statement is: "If \( (x,y) \) is on the graph of \( f(x) \), then \( (-x,-y) \) is on the graph of \( -f(-x) \)."
