    This is very simple as all you would need to do is simply make a table of values and substitute the value of a as + 1, and see what coordinates will be obtained, by plugging in any value for X and finding a y coordinate. Now do the process again with - 1, and eventually you will see after plotting which direction the parabola will open.
