Extrapolate Values from Fit?


Maybe this is very simple, but I’ve looked all through manual and online documentation. I have a histogram that I am fitting with a simple polynomial. This is no problem. I’d like to extrapolate the x values or solve x values for a given y value in the fit. Of course, I could take all the parameters and solve this but it seems to me this must be built in.

Any help???

Cut me some slack if this just completely simple. I have looked.



I guess Eval() does it fine. Sorry should have seen that.
