This demonstrates that movement of the graph to the
right means adding an h (>0) in the standard form
y = a (x - h)
subtracting an h (<0).

Notice that movement of the
basic y = x
by 3 units in the direction of
the x-axis is equivalent to the
addition of 3 to the x -intercept.

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