Exercise 5.17, p. 123

• If the range is just one point (a = b), then the point where function is smallest is a

• Otherwise, the point where the function is smallest is a if f(a) is less than the smallest value on the range [a+1 .. b]

• Otherwise, the point where the function is smallest is in [a+1 .. b]

     (define integer-in-range-where-smallest
       (lambda (f a b) 
         (if (= a b)
             a
             ____ ? ____)))
