Function composing feeds the output of one function to the input of another function. Look at the implementation of compose and select the correct result of code execution def compose[A, B, C](f: B => C, g: A => B): A => C = a => f(g(a)) def f(b: Int): Int = b / 2 def g(a: Int): Int = a + 2 compose(f, g)(2) compose(g, f)(2)
