comment Why Function is compiled?
I certainly didn't downvote the question, I just can't think of who would be able to answer it. But you can wait and see if you want to, it's your choice.

comment Defined Function fails to Evaluate
This invariably happens because the definition for f doesn't match the given arguments. In this case a_list doesn't match {1,2,3} because the head of {1,2,3} is List and you specified list.

comment Expand the plotting range
It doesn't plot imaginary numbers (such as the root of a negative number) because the plot coordinate system is over the real cartesian 2D space. You can use Re to obtain the real component and plot that.

That list is just a partial list, things are more complicated. Jagra's answer is as authoritative as it gets in this regard I believe.

comment Finding number of pixels with certain RGB color in an image
@M.R. I don't think that will work in general, will it? You're counting the number of zeros in the blue color channel - but let's say there is a pixel like {50,150,0} then your method will be wrong.

Count is much faster if you tell it to only look up to level 2 instead.

comment Can the increment in Manipulate, Table, Range, etc. be subject to an If statement?
You can join two ranges together: Join[Range[-2, 0, 0.025],Range[0.01, 2, 0.01]]. But you can't use If.
