1 Answer1 You are right since the vertex is above the focus, the parabola must open downwards So p = − 10 and the parabola has equation ( x − 1) 2 = − 40 ( y − 2) Note that the right hand side is never negative because for all points on the parabola y ≤ 2 (because the parabola opens downwards)For a parabola in standard form (x−h)2 = 4p(y−k), ( x − h) 2 = 4 p ( y − k), we know that the vertex is (h,k) ( h, k) the focus is (h,kp) ( h, k p) the equation of the directrix is yVertex V = (2,1), Focus F = (2,0) X coordinate 2 is common, so parabola is vertical and focus is above vertex, so it opens upwards Distance p between vertex and focus is (0(1) 1 unit, so length of focal chord or latus rectum is 4p, 4 units St
