The function is
and
.
The function is of the form
.
So the graph of
is the graph of
is reflected in
axis and shift towards right side.
Compare
with
, where
.
Since
the graph of
passes through the points,
,
and 
passes through the points
,
and
.
Next graph the function
by applying transformation to the original function.
The graph of
passes through the points
,
and
.
Graph the functions
and
.

The graph of
is the graph of
is reflected in
axis.
Graph of the functions
and
is \ \
