Ok, I know how to do this but I don't have a graphing calculator now so. Question is:
(2, 13.2) (27, 40.5) (58, 82.7) (82, 172), find exponential function f(x) = ba^x
Prove it, your method doesn't account for the last two points so it's not right I tried it.
This should be a very easy problem if I plot the points in the graphing calculator and find Exp Reg. Please someone with a graphing calculator kindly do it for me I don't have one.
Thanks I don't know there's a thing a called Regression Applet before. I got my answer using it (Exponential Regression Applet).
