How do I enter a quadratic and cubit-fit equations?
 

I have a data set the I want to evaluate using quadratic and cubit fits- can
someone provide the proper equations? Adn what about plotting the funtions?

How do I enter a quadratic and cubit-fit equations?
 

1) read Help to learn about Trendlines - make an XY chart first
2) visit my site to learn about LINEST to find polynomial coefficients

3) to lean about charting - buy a book or visit
