# Is mathematica unable to plot Getting error messages from a function with Integrate?Plot expression containing an integral

This should be a really simple question, but I just got confused.

Plot[Integrate[x, x], {x, -5, 5}]


Integrate::ilim: Invalid integration variable or limit(s) in -4.9998. >>
Integrate::ilim: Invalid integration variable or limit(s) in -4.79571. >>
Integrate::ilim: Invalid integration variable or limit(s) in -4.59163. >>
General::stop: Further output of Integrate::ilim will be suppressed during this calculation. >>

And it gives no graph of the function.

At first I was trying to plot a function that MathematicaMathematica is unable to integrate, but the problem exists with even simple functions.

By the way, MathematicaMathematica refuses to integrate Log[Abs[x]] while Wolfram|Alpha is able to give the result.

I apologize in advance if this is my stupid mistake.
