The exponential function is .
(a)
\Property : reflects the graph of
about
axis.
Graph :
\Graph the functions and
.
Reflect the graph of about
axis.
Observe the graph ;
\Hence the graph of the function is refected about
axis is
.
To find reflection of the graph about the line
, shift the graph of
by
units upwards.
Property : shifts the graph of
to a distance of
units upwards.
Graph :
\Graph the function .
Shift the graph of by
units upwards.
Observe the graph :
\The graph of the function is shift
units upwards.
Hence the graph of the function shift
units upwards is
.
The exponential function is .
(b)
\Property : reflects the graph of
about
axis.
Graph :
\Graph the functions and
.
Reflect the graph of about
axis.
Observe the graph ;
\Hence the graph of the function is refected about
axis is
.
To find reflection of the graph about the line
, shift the graph of
by
units right.
Property : shifts the graph of
to a distance of
units right.
Graph :
\Graph the function .
Shift the graph of by
units right.
Observe the graph ;
\The graph of the function is shift
units right.
Hence the graph of the function reflected about
is
