I am trying to do define set function as follows:
Let A=[a,b]
(closed set);or (a,b) (open set) or (a,b] or [a,b) (semi
closed sets)
f(A) is piecevise function with respect to A (closed, open
or semi closed)

Let f(A)=2a-b if
if A=(a,b)
if A=(a,b]
=5a-3b if

How can I define this function? I tried "Switch"
command but because of [. ],[. ),... symboles It did not
