To analyze the statement involving a point on the graph of \( f(x) \) and its relation to \( -f(-x) \), we start by noting that if \( (x, y) \) is a point on the graph of \( f(x) \), this means:

\[ f(x) = y \]

We want to look at the point \( -f(-x) \). To find the \( y \)-coordinate of this point, we first evaluate \( -f(-x) \):

  1. Substitute \( -x \) into \( f(x) \): If \( (x, y) \) is on \( f(x) \), then \( f(-x) \) gives us the value when the input is \( -x \).
  2. The \( y \)-coordinate for the point corresponding to \( -f(-x) \) would thus be: \[ -f(-x) \]

Now considering the transformations:

  • \( f(-x) \) reflects the graph of \( f(x) \) over the y-axis.
  • \( -f(-x) \) reflects that result over the x-axis.

Thus, if \( (x, y) \) is a point on the graph of \( f(x) \), we have the following final relationship based on the transformations applied:

  • The transformation gives us \( (-x, -y) \) on the graph of \( -f(-x) \).

Therefore, the statement that best describes the relationship is:

If \((x, y)\) is on the graph of \( f(x) \), then \((-x, -y)\) is on the graph of \( -f(-x) \).
