a transition of 7 units right shifts it completely to the right side of the y axis.
a transition then of 5 units down shifts it completely into the second quadrant (positive x, negative y). it is now completely below the x axis and right of the y axis.
and now a reflection across the y axis keeps it below the x axis but shifts it completely to the left of the y axis. and it is therefore more in the third quadrant (negative x, negative y).
The focus is left of the vertex, so the parabola opens to the left. The vertex is halfway between the focus and directrix, so the directrix is the vertical line x = 2
