I believe I was able to successfully solve this problem numerically but am having trouble graphing it. The functions I got are a bit large so scaling the moment diagram is difficult. Also, are the equations functions of x as in meter values (for example 0.4m) or functions of d (for example f(1) outputs the value at 1d)?
I think you have to graph it using meters and not "d" since that's what the professor did during lecture. Also it makes more sense to use the numerical meter values since we're basing our calculations off of that.
I thought that the lecture video for Example 2 in Period 27 did an excellent job in explaining a problem that is very similar to this. Consult that video if you want to check your work and make sure your final answers are accurate.
It is helpful to break up these problems as, finding out what you know about the full FBD, then breaking into segments, and for each segment summing the forces and then summing the moments at P.
When doing this it was helpful to break the problem down into parts. I started from the left and worked to the right and it made the problem quite easy to break down.
