Hi, It's been so long since I took any math classes! Please bear with me. I have sets of three points on various exponential graphs such as 0=100, 30=138, and 60=392 (x and y). I have found manually that this equation is somewhere very close to y=.0025x^2.85+100. I CAN do these manually (plugging in numbers into Excel and modifying them to hit the desired points on a graph), but I have a few HUNDRED of these sets. Is there a faster way? Hopefully that I can put in the 0, 30, and 60 values and Excel can determine the equation? (The built in Excel equations I have used from the graphs so far are completely wrong for what I am doing.)(adsbygoogle = window.adsbygoogle || []).push({});

Please shoot me an email if you can help me! It will help me so much! (Please keep it simple!)

Thanks a lot!

Mike
