  1. Well, you really did not ask a question. All you did was give the equation fort a parabola. So what?
    y = x^2 - 2 x - 3
    do you want to know where that is zero? Where the vertex is? how it looks?
    if you want the two zeros, just factor it
    y = (x-3)(x+1)
    that is zero when:
    x = 3
    and when
    x = -1

    so the vertex is halfway between
    x = (3-1)/2 = 1
    then y = 1-2-3 = -4
    so vertex at (1,-4)

    what else about it?
