I think there is mistake in graph of |X+1|-|2X-2| It should be constant(with slope =0) except b/w roots, as you have said. please clarify, Thanks Reply
No Vaibhav, since the slopes are different the one with the higher slope (2 in this case) will determine the shape. regards J Reply
Sir, is it possible to check if a given modulus function will have a maxima or minima without plotting? Like in this case? Reply
Jim, see my reply to your earlier comment. You should be able to work out the answer to this from there 🙂 regards J Reply
Sir, In the last question if we want to calculate the minimum value of |x+1|-|2x-2|, will it be (-infinity) and the maximum value 2 at x=1? Regards, Adorini Reply

Thanks a lot sir.
Doubt cleared 🙂
I don’t know what you replied to Jim please share
Having doubt how you plotting the red graph i.e the output graph.
Sir,
In the last question if we want to calculate the minimum value of |x+1|-|2x-2|, will it be
(-infinity) and the maximum value 2 at x=1?

Yes it will!
