[ASK] Reflected Parabola
Determine the reflection of a parabola
by the line y = -x.I know how to do it graphically, but please tell me how to do it algebraically.
Actually I never watch Star Wars and not interested in it anyway, but I choose a Yoda card as my avatar in honor of our great friend bobbym who has passed away.
May his adventurous soul rest in peace at heaven.
