title: Excel shows incorrect polynomial trendline function
body: <p>I'm trying to create a polynomial function that fits my data in column H.  Column I are the x values, and column J is the function that the charts polynomial trendline shows. So why is my result (see orange line) not equal to the trendline function? What's going on here?</p>
