Question 1183277
.


Regarding making the plots,  my position is principled:


<H3>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It is the student' job, and it is the student 


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;who MUST DO IT on HIS or HER own, without asking for help from outside.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If the student does not make HIS (or HER) job, he (or she) is simply a bum.</H3>


Therefore, &nbsp;if you do not want to have &nbsp;(to make) &nbsp;a scandal, &nbsp;do this job on your own 


and do not include such requests into your future posts.




Regarding your request on finding the roots &nbsp;(part a), &nbsp;I can not believe to my eyes.


I know for sure, &nbsp;that the students study / learn the problems on finding maximum/minimum of quadratic functions

only after they learned solving quadratic equations. &nbsp;&nbsp;It is a standard &nbsp;NECESSARY &nbsp;PRE-REQUISITE.


So, &nbsp;if you can not solve a quadratic equation and can not find its roots on your own, &nbsp;then you simply are in wrong class.



If you are not agree with me, &nbsp;then &nbsp;&nbsp;PLEASE &nbsp;&nbsp;clarify.
