Linear function problem

Can anybody give me an example of a function with the properties f(x+1)<f(x) and f(0)=1

Oh, linear.  I neglected that part.  Oh, and fuck you asshole

>>6
And another thing, go fuck yourself.  The OP didn't mention linear in his sentence so I neglected that requirement, not recalling the subject title as I was thinking.  My function works according to the restrictions fine.  It's just not linear.

Oh, and fuck you

Anyway, I found a simpler function, which also isn't linear (eat it >>6):
f(x) = -(x^3) + 1
