Graph :
\1. Draw a coordinate plane.
\2. Plot the coordinate points.
\3. Then sketch the graph, connecting the points with a smooth curve.
\Observe the above graph :
\Domain of the function is .
Range of the function is .
Find -intercept by substituting
in
.
Apply definition of logarithm : if and only if
.
intercept is
.
Find -intercept by substituting
in
.
.
Since is not in the domain of logarithm
-intercept not exist.
Observe the above graph the function does not have horizontal asymptote.
\The equation of vertical asymptote of graph of the function is
.
Thus the vertical asymptote of graph function is
.
End behavior : and
.
Increasing over the interval : .
