Q2) (30p) Higher-Order Functions: Define a higher-order function in Haskell named applyTwice that takes a function f and a value x as arguments and applies the function f twice to x. The type signature of the function should be: applyTwice::(a->a)>a->a For example, if the function f is defined as double :: Int -> Int (doubling a number), then applyTwice double 3 should return 12
