A parabolic mirror is silvered at inner surface. The equation of the curve formed by its intersection with X-Y plane is given by `y=(x^(2))/(4)`. A ray travelling in X-Y plane along line `y=x+3` hits the mirror in second quandrant and gets reflected. The unit vector in the direction of reflected ray will be
