I took Algebra II forty years ago and I have to adapt the skils to Excel 2010 spread sheet and graphs. I was there when Noah launched the Ark so you know there is a big gap in my learning experience.
Looking to shake the dust of my Excel skills and old Algebra skills using Excel
I took Algebra II forty years ago and I have to adapt the skils to Excel 2010 spread sheet and graphs. I was there when Noah launched the Ark so you know there is a big gap in my learning experience.
My problem is f(x)=ax^2+bx+c and the graph passes (1,- 9), (3,7) and (4,12) then a=? b= ? and c=?. I have read several answers and have my chart set up with Profit(x), Selling Price and Cost, but the only line chart have two lines and I am stuck!!!
