Find the vertex, focus, and directrix of the parabola. Graph the equation. (x71)2=8(y73) The vertex of the parabola is (Type an ordered pair.) The focus of the parabola is (Type an ordered pair.) The directrix of the parabola is . (Simplify your answer. Type an equation.) Use the graphing tool to graph the parabola. A mirror is shaped like a paraboloid of revolution and will be used to concentrate the rays of the sun at its focus, creating a heat source. If the mirror is 22 feet across at its opening and is 8 feet deep, where will the heat source be concentrated? The heat source will be concentrated about feet above the bottom of the mirror.
