Question 08 (f) 

Let Sketch the graph of ƒ, indicating all you have found in the previous parts of the question. 
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! 
Hint 

Try (lightly) shading out the portions of the axes where the function is undefined. Then try adding in each piece of information from be, one step at a time. 
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Please rate my easiness! It's quick and helps everyone guide their studies. Using the information from parts (a)  (e), we draw the graph as follows. First, we know that the function is undefined outside of so we will shade out that portion of the graph. Now we add in the two xintercepts at and . We also include the information about the asymptotes  both and were asymptotes, with the function going to . Finally, incorporating the information from (d) and (e) about increase/decrease and concavity, and the maximum at x = 0, we connect the dots and finish the drawing.
