Similar problem:
Intersect does not work for these two objects: f(x)=80*1.2^x and y=500
Version 6.0.605.0offline
Intersect doesn't always provide you a solution (that's because of how things are calculated internally). If you don't get a solution that way you can try the command Solutions( f = 500) which gives you the solution l1={10.05}
Thank you. This also works.
My own workaround with my students was to solve it as an equation in CAS (NSolve 80*1.2^x = 500), but in doing so I felt that the visual effect was lost. Well, I still had the lines intersecting on the screen, so they knew what I was going for, but they were left with an impression that GeoGebra is difficult to use. Your solution is a bit better than mine in that regard, but it would still be nice if the intersect would give the answer straight away. My comment is not meant as a disrespect to your helpful answer, but if someone developing the algorithms is also reading this, maybe it is possible to find a way to make intersect work in similar cases?
Thank you for your time!
Thanks, we'll improve it soon so that this works!
Fixed for next release
v612 now released
