Heres my thought, since the left side limit, by its definition, the in the approaches 0. So, I figured (and this is where I needed some help verifiying this assumption) I figured that all I needed to do is show that approaches 0 since its the same function . Does that reasoning make sense? And if that reasoning it valid, then we have:
thus if we set then it shows that approaches as approaches , right?
