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

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}]
