So here is what I need to do within Maple.  I have to define a piecewise function and then determine left and right hand derivatives at a certain x value.  Then determine the whole derivative and graph both parts.  I am just pretty new to Maple so it is still fairly confusing and I cannot determine the exact commands that I need.

So I am fairly new to Maple and cannot figure this out.

I had to define and equation and then differentiate it and then evaluate this derivative at 2 and now I need to solve the derivative where the derivative=0 for x.  I can do this real easy on paper but I cannot figure out the right set of commands to do so in Maple.  Thank you
