To find the point that must be on the graph of \(-f(-x)\) given that the point \((7, 43)\) is on the graph of \(f(x)\), we need to perform two transformations:

  1. Horizontal reflection: The first transformation \(f(-x)\) reflects the graph across the y-axis. Thus, the point \((7, 43)\) becomes \((-7, 43)\).

  2. Vertical reflection: The second transformation \(-f(-x)\) reflects the graph across the x-axis. Thus, the point \((-7, 43)\) becomes \((-7, -43)\).

Combining these two transformations, the point \((7, 43)\) results in the point \((-7, -43)\) on the graph of \(-f(-x)\).

Therefore, the point that must be on the graph of \(-f(-x)\) is \((-7, -43)\).
