I need these three functions plotted in matlab, what am i doing wrong that im getting only 1 function?

b. When you look at your plot, you can imagine that there are an infinite number of lines that connect State 1 and State 2. That means that there are an infinite number of paths or thermodynamic processes to get from State 1 to State 2. Let's plot three of them in one plot, add these three functions between your two state points that you plotted in the first part. a. P=0.1 b. P=-0.2V2 +0.3V C.
