I have a set of data that is non-linear and believe it will fit a power trend
equation. I have been unable to locate a program that will curve fit the
data.

the trend line in the Graph Function.

Linest

You can see how Bernard Liengme solves for the coefficients of a polynomial
curve using LINEST. Perhaps you can adapt a similar approach to working
with your 6th order polynomial equation.

Supplementing Tom's response:

Create a chart with the data. Then, in the chart select the plotted
series then select Chart | Add Trendline... and select the appropriate
option.

Also, in addition to Bernard's web page that Tom referenced, you may
