How To Solve These Equations? (Deleted Post)

[mymachine]

I don't understand and would like to have a clue or hint on how to solve below equations:

$F(t)=$

$\frac{1}{6}(7-t)^{2}(1,2)+\frac{1}{3}(-t^{2}+12t-34)(3,5)+\frac{1}{6}(t-5)^{2}(6,2)$__________if__________$5≤t<7$

and

$\frac{1}{3}(8-t)^{2}(3,5)+\frac{1}{3}(-2t^{2}+30t-110)(6,2)+\frac{1}{3}(t-7)^{2}(9,4)$__________if__________$7≤t≤8$

NOTE: I already post above question previously but not being displayed. I think it has been deleted due to some reason that I don't know.

Also, what is meant by "This forum is not for homework or any textbook-style questions."?

So, what is the purpose of this forums?

What kind of questions could be posted in this forum if not a homework or textbook-style question?

Thank you

The homework forums are here:

https://www.physicsforums.com/forumdisplay.php?f=152

The PF Global Guidelines give some information about what should be posted in the homework forums versus the main forums such as this one:

Any and all high school and undergraduate homework assignments or textbook style exercises for which you are seeking assistance are to be posted in the appropriate forum in our Homework & Coursework Questions area--not in blogs, visitor messages, PMs, or the main technical forums. This should be done whether the problem is part of one's assigned coursework or just independent study. The reason for this is that the scientific and mathematical sections of Physics Forums are to be reserved for discussions and not academic assistance. Since graduate level assignments are meant to be more thought provoking (and hence more worthy of discussion), graduate level questions will be allowed in the relevant part of the main section of PF, provided that the graduate student attempts the problem and shows his work.

mymachine,
You already received a warning for posting the first thread, so I have locked this thread. As jbunniii, homework-type questions should not be posted in the technical math sections. Instead, they should be posted in the Homework & Coursework section.

If you post your question there, you will be presented with a template that asks for the problem statement, relevant equations, and your efforts.
