First try graphing "Total Revenue" as a function of "Advertising". That should give you an idea of what kind of function to try.
I was given this assignment and have no idea how to even start! Do I need to make a stat graph? Which columns of information do I use? Will the equation be in ax^2 +bx+c form? And how can I use it?
Can someone find the equation? Is it: 2.1190x^2+6.6429x+11.1667?
Thank you so much in advance!
