Assume that you are considering enhancing a machine by adding a special feature to it. The percentage of time (the original run time before the feature is added) that the machine can be run using this new feature is denote as p%, and, during this portion of time, the machine with this new feature runs f% faster than the old one without it. Required:
a. Determine the overall speedup for each of the following:

i. f = 100, p = 100
ii. f = 100, p = 50
iii. f = 400, p = 50
iv. f = 400, p = 20

b. Draw a graph that plots together each of the two speedup functions for f = 100 and f = 400 in terms of p (y-axis being the speedup and x-axis being p).
