Sure it looks different as expected, but that doesn't say anything about the
usefulness.  You can just use the function directly you want to get rid of the
"pixel" effect.  Image functions are after all there specifically to get an
image of the function.  If you use them for something else, well, what do you
expect?

I really see no point in explaining that an image is composed of pixels while
a function is evaluated for every point with its precise coordinates (or
whatever way to explain it), because that is the only way they can and do work
everywhere...

No problem.
