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)Start studying Parabola (xh)^2=4p(yk) Learn vocabulary, terms, and more with flashcards, games, and other study tools6 Which shape is defined by the equation y 2 = 12x?

If a parabola has a horizontal axis, the standard form of the equation of the parabola is this (y k)2 = 4p(x h), where p≠ 0 The vertex of this parabola is at (h, k) The focus is at (h p, k) The directrix is the line x = h pThen graph the parabola The equation is in standard form and the squared term is x, which means that the parabola opens vertically Because 4p = 12, p = 3 and the graph opens upward The equation is in the form (x — h)2 = 4p (y — k) , so h = 3 and k = —4 Use the values of h, k, and p to determine the characteristics of the parabolaThis is a topic level video of Graphing a Parabola of the Form y = a(xh)^2 k for the ASU College Algebra and Problem Solving CourseJoin us!https//wwwed
