Notice that movement of the basic y = x2 graph to the right by 3 units in the direction of the
This demonstrates that movement of the graph to the right means adding an h (>0) in the standard form y = a (x - h) 2 + k and movement to the left means subtracting an h (<0).

Notice that pinching or closing the basic y = x 2 graph is equivalent to increasing an a (>1) within the standard form y = a (x - h) 2 + k and broadening the graph is equivalent to decreasing an
a(<1).
