Functions inside list

I have a function berekenMaxWidth[beta_] which only gives the correct output 
when beta is numeric so I use 
maxWidth[beta_?NumericQ]:=berekenMaxWidth[beta]. Otherwise I get incorrect 
results, for instance when trying to plot berekenMaxWidth[beta].

This function represents a curve that will be of importance between two 

My problem arises when I try to give the function to a list of the shape 
{{xLow,xHigh},relevant curve function}.

If I do: {{xLow,xHigh},maxWidth[beta]} , I get {{xLow,xHigh},Infinity} in my 
list instead of the function. This is incorrect. I need the  list for 
instance to find intersections between curves in the x-domain. So for the 
input in the list I need the correct function to be returned instead of 

So how can I give along the function to the list so that it works correctly?
