A program is run on a computer with multiple processors. When a computation is run in parallel mode, it is 20 times faster than if the computation were done on a single processor.

In Excel, draw the speedup graph (Y-axis) as a function of program fractions enhanced (X-axis) in increments of 0.05. By observing the graph, what conclusion can be made (be descriptive and clear)? You need to show the graph in fraction increments of 0.05.

I need to know the instructions for creating this graph in Excel.
