Exercise 1.42: Let f and g be two one-argument functions. The composition f after g is defined
to be the function \( x \mapsto f(g(x)) \). Define a procedure compose that implements composition.
For example, if inc is a procedure that adds 1 to its argument,
((compose square inc) 6)
49
(define (compose f g)
(lambda (x) (f (g x))))
(define (square x) (* x x))
(define (inc n) (+ n 1))
> ((compose square inc) 6)
