    \[y = \sqrt{x + 2}\]Just plug in the coordinate choices with their respective variables

    like he said, the numbers are coordinates (x,y) so \[4=\sqrt{-6+2}\] this is square root of -4 which is imaginary \[-3=\sqrt{7+2}\] this is 3 not negative 3 so this one is a no so i would go with D none of the above
