Y=-2 (x-4) ^2-6

The - 6 makes it shift from origin (0,0) to (0,-6)

Then the - 4 inside with x, makes it shift to the right by for, so the center would be now instead of (0,0), (4,-6).

As it has a negative A factor, it is a parabola open downwards, so the center is the maximum value.

Answer: (4,-6)

Hope you get it!
