Question 607327
<font face="Times New Roman" size="+2">


You are off a decimal place on your intercept.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ =\ 1.6x\ +\ 0.2]


has an *[tex \LARGE R^2\ \approx 0.88], not too bad.


On the other hand


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ 0.35x^2\ -\ 1.58x\ +\ 6]


has an *[tex \LARGE R^2\ \approx 0.96]


and


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ 0.18x^4\ +\ 3.13x^3\ -\ 19.42x^2\ +\ 49.99x\ -\ 40.5]


where *[tex \LARGE R^2] is very close to 1.

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
