### Problem with solve

Hi, I'm very very new in Sage. I have a problem trying this:

x=var('x')

f=10(1-exp(-0.23(x)))^2

g=20(1-exp(0.23(x-14)))^2-10

I'm want to get the intersection point(s). From Maple, I know there is three, but when I try to solve for x:

solve(f==g,x)

Sage gives me that [ ]! What does it mean? Thanks in advance 2 No.2 Revision
