How's this?
f[x_]:=x^3-x+1
g[x_,y_,s_]:=Which[
Or[x==y,s[x]==s[y]],"Unknown",
Xor[s[x]>s[y],x>y],"Decreasing",
True,"Increasing"
]
g[2,3,f]
g[2,3,-#&]
g[2,2,f]
g[2,-2,#^2&]
"Increasing"
"Decreasing"
"Unknown"
"Unknown"

How would one pass one function to another?
I need to be able to define functions in the following fashion:
f[x_]:=x^3-x+1
g[x_,y_,somefunction?]:=If[somefunction[x]>somefunction[y],"Done","Waiti
ng")
to be able to later on evaluate
g[2.,3., f?]
I have tried couple of paths with no success and would really like to
avoid using global function in function g.
All the best...
