See the Intersect wiki page for the correct syntax https://wiki.geogebra.org/e...

If you use x instead of h as a variable to define your V(x), the Intersect command works.

So just change V(h) to

`If(0 ≤ x ≤ 170, 2.4 (6.5^x))`

Hello! :-)

I think the command

`Intersect( <Object>, <Object> )`
needs special kind of functions like conic or polynomial functions to calculate intersection points excactly.

In the two examples one function is not of this allowed kind (one is an exponential and one is a rational function), so better use/try one of these commands.

```Intersect( <Object>, <Object>, <Initial Point> )

Intersect( <Function>, <Function>, <Start x-Value>, <End x-Value> )```

Here the intersection point(s) will be identify by a numerical method.

kind regards
