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 x-values. 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 Infinity. So how can I give along the function to the list so that it works correctly?
