Hello, Ahe!
Just "talk" your way through it . . .
(1) is negative. .At the graph is below the xaxis.
. . . is negative. .The graph is decreasing.
. . . is negative. .The graph is concave down.
It is shaped like this: Code:
2
     +     
* :
* :
o
*
*
(2) does not exist.
. . .There is a vertical asymptote at
(3) There is a local maximum at (2,3)
(4) There is one inflection point on (0,2).
Since the curve is concave down at the maximum (2,3),
. . it was concave up to the left of the inflection point.
It looks something like this: Code:
 (2,3)
* o
 * : *
 * o : *
 * * :
 * :
++
0 2
(5) There is a horizontal asymptote: .
I would guess that the graph looks like this: Code:

* o
 * : *
 * o : *
 * *: : *
 * : : *
2  : : *
++++*
:  1 2 *
     :    +                   
* :  y = 1
* : 
o 
* 
* 
*
