[Haskell-beginners] Selecting Arguments in Function to Feed Map

Dear All, Suppose you have the function f x y z = x*y +z and that you want to iterate it on a list z=[1,2,3,4], with x=4 and y=3 then you would do the following map (f x y) z. Now consider the case in which the list is given by y e.g. y=[1,2,3,4], with x=4 and z=3. How can you iterate f on y (i.e. its second argument) while keeping x and y fixed? Lorenzo
