Webequal to each other and solve for y. to derive the equation of the parabola. We do this because the distance from (x, y) to (0, p) equals the distance from (x, y) to (x, − p). √x2 + (y − p)2 = y + p. We then square both sides of the equation, expand the squared terms, and simplify by combining like terms. WebSay we have the equation: Y-k=x^2. To see how this shifts the parapola up k units, substitute x with 0. The equation will simplify to y-k=0. So for the equation to be true y needs to be equal to k; like how in factored form x needs to be the inverse of the constants a or b to equal 0, i.e (x-a) (x+b)=0. Comment.
