(-7, 43)
we know f(7) = 43, but we have no idea what f(-7) is.
So we cannot know -f(-x).
If f(x) is even, then yes, -f(-7) = 43

If f(x) is even, then yes, -f(-7) = 43
You are correct. Without any information about the function f(x), we cannot determine the point on the graph of -f(-x). We can only deduce that if f(x) is an even function, then -f(-7) would indeed be 43.
