Types in Haskell

I've tried using :t and :type but there's a parsing error. How do these need to be defined so that Haskell can determine their types?

Fill in the blanks. 1. What is the type of the function f? 2. What is the type of the function g? g x y z = (x, (y, z)) What is the type of the function h? hfx= 3. (x,fx) 4. What is the type of the function p? p xs = xs = reverse xs
