@@ End of Day Wrap Sat 20/12/14 Sydney, Australia Time 12:35 am (Sun morn really) ♬
Today was very quiet. There were a few questions and these were well answered by geno3141, happy7, Alan and CPhill. Thanks guys.
Zegroes dropped in for a visit - that was nice. Please Rosala will you return at least for a visit. :(
I did not set aside any interest posts. So a good evening/day to you all and enjoy the rest of your weekend :)

I do not know but if you find one it would be great to share it with us.
I would also like a app where you could name some points and it could tell you some equations that would fit and/or draw the graph for you.
Maybe you could specify further restrictions like polynomial of degree 3 etc
That would be really good :)
Maybe one of the programs I already use does this and I just don't know about it?
It is possible that this equation was meant to be:
in which case, multiply all terms by x2 -9
Express x2 - 9 as (x+3)(x-3) and cancel as appropriate
Expand bracketed terms and collect like terms on the same side
OK Melody, I know it was you who deleted my Happy birthday greeting to CPhill, because he hasn’t been on since I posted. He probably has a big hangover from celebrating.
Only you, happy7 and Goldenleaf (and me) have sent him Birthday greetings. Seems like there should be more.
My greeting was very sincere. Maybe you should restore it. We wouldn’t want him to feel unloved!
