$\"\"$

\

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.

\

The critical points are $\"\"$ , $\"\"$ and $\"\"$ .

\

Therefore it has a either local maximum or minimum at the critical points.

\

Graph :

\

Graph the function such that all the conditions are satisfied :

\

Using above tests,

\

$\"\"$ represents that $\"\"$ is increasing on $\"\"$ .

\

$\"\"$ represents that $\"\"$ is decreasing on $\"\"$ .

\

$\"\"$ represents that $\"\"$ is concave upward on $\"\"$ .

\

$\"\"$ represents that $\"\"$ is concave downward on $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Graph the function is drawn such that all the conditions are satisfied is

\

$\"\"$ .
