Not a Problem

I get "Undefined" when trying to find intersection between F(x)=0.987^x and y=30000. Seems to be a problem for the specific value of 30000, if I change to y=30000.01 it works just fine. See attached screenshot for version number. (Pretty sure it's the latest version.)

Intersection(F, f, -1000, 0)

Also try

g(x)=Invert(f)
g(30000)
