Does anyone know a geometrical (i.e. not algebraic) reason that the sum of two parabolas is still a parabola?
@mandy3284 @squishythinking I would approach that by drawing inflection points. Show that when x^2 + x^2 [draw] no change # inflect points

@mandy3284@squishythinking you can even show that on an x-by-x basis, points are only linearly offset (draw vertical lines btw curves) -
@mandy3284@squishythinking Twitter has to be about the most ironic medium for trying to depict this. Lmk if this !make sense, I try to draw -
@starsandrobots@mandy3284 Sorry, I'm not quite following. Agreed re: Twitter, but if I asked somewhere else, you wouldn't have seen it! -
