(solution) (1 pt) Consider the function shown below. What type of function

(1 pt) Consider the function shown below.

What type of function is shown in this graph? 
 A. density function (pdf) 
 B. cumulative distribution function (cdf)

(Be sure that you can give reasons for your answer.)

What value must  have? 
 

Finally, sketch and label the other function (that is, sketch and label the cdf if the problem shows a pdf, and the pdf if the problem shows a cdf.) (You will not be able to enter this in the web homework, but should be able to identify the (x,y) coordinates of all significant points on the graph and carefully explain how you found them.)
