Hello, nath_quam!
What do the graphs looks like and what are their key points?
1x)^3(x3)" alt="b)\; P(x) \:= \
1x)^3(x3)" />
has xintercepts:
As . . . The graph rises to the right.
As . . . The graph rises to the left.
You should be able to sketch the graph now . . .
Code:

You can use the derivative to locate the exact positions
. . of the maximum and the two minimums.
1x)^3(x3)" alt="b)\;\;P(x)\:=\1x)^3(x3)" /> has xintercepts:
The graph rises to the right and to the left.
We find that is an inflection point
. . and there is a minimum at
