Hello guys i need your help for a quadratic function assignment. the question
reads as follow:

the sales figures for a business are as follow for the first six months of
the year:
40,000$, 44000$,  52000$, 64000$, 80000$, 84000$. the owner beleives that
the sales curve can be approximated by a quadratic function. find the best
quadratic fit to the data, and use it to estimate the projected sales for
the rest of the year.

thanks a lot in assisting me for this one. I need the code that need to be
input to Octave to acheive the solutions.

many thanks in advance...
