WebFocus of Parabola: The focus of parabola y2 = 4ax y 2 = 4 a x is (a, 0). The parabola is defined with reference to the focus of the parabola and the parabola is the locus of a point that is equidistant from the focus and directrix of the parabola. WebGiven the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2. Equivalently, you could put it in general form: x^2 + …
