Step 1:

\

The conditions are \"\", \"\", \"\" and \"\".

\

First derivative test: \ \

\

If \"\" , then the function is decreasing.

\

If \"\",  then the function is increasing.

\

\"\" represents at the point \"\" the function is decreasing by the first derivative test.

\

\"\" represents at the point \"\" the function is increasing by the first derivative test.

\

Graph the function by satisfying all above conditions.

\

\"\"

\

Solution:

\

\"\"
