Is there a way to do a polynomial fit and an exponential fit on a single plot at two different intervals in the plot?

For example: I have a plot of a an array containing y and x variables. The graph has three distinct curves from the data. I want to approximate an exponential function for one interval, a polynomial function for the second.
How would I go about doing this?

Do you exactly know the interval for which you need to fit an exponential and the polynomial function?

Hi Ken,
If you know the interval for the three distinct curves, then one of the approach would be to divide your data into 3 subsets and fit respective functions to those subsets. Then you can easily plot the fitted functions onto the same plot.
Hope this helps.
