Question: Haskell 6. Consider the function pair x y = (x,y) What is its type? (5 points). Why can x and y correspond to different types

Haskell
6.
Consider the function
pair x y = (x,y)
What is its type? (5 points). Why can "x" and "y" correspond to
different types here, as well? (5 points)
7.
Consider the function
double x = x*2
What is its type? (5 points). Why are there the particular class
constraints on "x" and the return type of "double"? (5 points)
