Question: Why wont my function plot over my entire domain?

I have a function that I want to plot from x=0..5 , when I ask it to plot over this range it will not plot from x=0..1 it will just go from x=1..5. However, If I ask it to plot from x=0..1 it will plot that... so then I have to splice the images together in display. 

Has anyone seen this problem? Is it something easy and stupid that I am missing? 

Function of interest attached in file.
