Disclaimer: This is not a "Do my homework" type of question. Instead, this is, "I'm confused whether what I did is right or wrong?" type of question.

If I ignore negative signs in TVC value, everything other values come in positive form. But is it okay to do so? If not, then the solution I have written here should be correct.

Question and my solution toward it.

  • $\begingroup$ I agree with your note that TC should be >= 0. The Total cost function takes a really strange form with that negative Q^3. Instead of ignoring the sign you should defentively ask the author from that question why he is implementing such a strange Cost function. $\endgroup$ – Armenthus Jan 3 at 10:28
  • $\begingroup$ I wish I can ask the author. This was asked on the board exam. I wonder if they correct it over a phone call during the exam period. The question is really bad or might have been a typing mistake. @Armenthus $\endgroup$ – Pranav Jan 3 at 10:38
