Gayle graphs the parabola () + 1) = 12 (x -3). How does she proceed? Drag a value, coordinates, equation, or word to the boxes to correctly complete the statements. Gayle identifies that the vertex of the parabola is ! The parabola opens and the focus is units away from the vertex. The directrix is ! units from the focus. The focus is the point The directrix of the equation is ! Gayle plots the vertex and focus, and graphs the directrix as a dashed line. She then draws the parabola so that the focus sits inside the curve and the directrix does not intersect it. (3, -1) (3, 2) (6, -1) 3 6 12 X = 0 X=-2 y = -4 y = -6 up down left right
