Consider the function f(x,y) = x + y. (a) (2 points) Define this as a Haskell function in curried and uncurried fashion. Curried function: Uncurried function: (b) (2 points) What are the type signatures for the two functions you defined? Curried function's type: Uncurried function's type: Total for Quest (c) (2 points) Evaluate each function with the arguments x = 4, y = = 5. Explicitly show how the arguments are passed to the function, how you evaluate the body, and the final result.
