Exercise 1.43: If f is a numerical function and n is a positive integer, then we can form the n th repeated application of f , which is defined to be the function whose value at x is f ( f ( … ( f ( x ) ) … ) ) . For example, if f is the function x ↦ x + 1 , then the n th repeated application of f is the function x ↦ x + n . If f is the operation of squaring a number, then the n th repeated application of f is the function that raises its argument to the 2 n -th power. Write a procedure that takes as inputs a procedure that computes f and a positive integer n and returns the procedure that computes the n th repeated application of f . Your procedure should be able to be used as follows: ((repeated square 2) 5) 625 Hint: You may find it convenient to use compose from Exercise 1.42.
