Hi Rajeev,

Not sure how you are copying and pasting. It worked fine for me

Plot[Piecewise[{{-2*x^2 + (5*x^4)/4 - x^6/6, -2.5 <= x <= 2}, {-4.361979167, x < -2.5}}, 4/3], {x, -4, 4}]

Welcome to Wolfram Community! Please make sure you know the rules: https://wolfr.am/READ-1ST

The rules explain how to format your code properly. Posting code Images doesn’t help other members to copy your code. Please EDIT your post and make sure code blocks start on a new paragraph and look framed and colored like this.

int = Integrate[1/(x^3 - 1), x];
Map[Framed, int, Infinity]

You can also embed notebook or attach notebook.

This is the code that is generated.Since not sure why so, I decided to use the image option.

Not able to access the above code from the source https://www.wolfram.com/wolfram-u/introduction-to-calculus/functions.html that shows something different.

I clicked on it in the course page, then I pasted it in my notebook and it was copied correctly. I use V12.3.1 , but I believe it should work fine on several older versions too
