Go to num-solv and get 0= and go to right side of = and put d/dx in, hit enter which will place f(x) in the differential, make x=x! hit enter to enter solve template. Choose a guess and solve for x. You can then quit, press table, select 1 and enter getting f( make that f(x), enter and get f(x) value. Press x, enter, and get the value of x.

Sorry to bother but I'm running into syntax errors trying to replicate this.
- How do you make f( f(x)?
- how do you paste f(x) into the differential?

Can you do this step by step with a simple expression?
