The condition are :
\I/D test :
\If on the interval, then
is increasing on the interval.
If on the interval, then
is decreasing on the interval.
Concavity test :
\If for all
in the interval, then the graph of
is concave upward on the interval.
If for all
in the interval, then the graph of
is concave downward on the interval.
Graph :
\Graph the function such that all the conditions are satisfied :
\Using above tests,
\ represents that
is increasing on
.
represents that
is decreasing on
.
The critical point is .
Therefore it has a either local maximum or minimum at the critical point.
\ represents that there is a vertical asymptote at
.
represents that
is concave upward on
.
Graph the function is drawn such that all the conditions are satisfied is
\
