What is true of it

Fadd9 is F, A, C and G — 1, 3, 5 and 9 counted from F.

On an instrument that cannot reach all 4, the 5 goes first, in that order.

The easiest of the 5 fingerings below is 103011: 4 fingers, held at the 1st fret.

2 of them use open strings, which is what makes a shape quiet to change to.

The brass dots are F, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
