1. The reflection of a point $$(x, y)$$ over the $$y$$-axis is given by the transformation:
   $$
   (x, y) \to (-x, y)
   $$
2. For the point $$ Q(-2, 5) $$, applying the transformation:
   $$
   x = -2 \quad \Rightarrow \quad -x = 2
   $$
   $$
   y = 5 \quad \Rightarrow \quad y = 5
   $$
3. Therefore, the reflected point is:
   $$
   Q'(2, 5)
   $$
The reflection of point $$ Q(-2, 5) $$ over the $$ y $$-axis is $$ Q'(2, 5) $$.
