The following defines a function that calculates an approximation of the square root of a number, starting with an approximate answer (approx), within the specified tolerance (tol).

SqrRoot(number, approx, tol) = approx, if approx - number tol1. What limitations must be made on the values of the parameters if this method is to work correctly? 2. Write a recursive version of the function SqrRoot. 3. Write a nonrecursive version of the function SqrRoot. 4. Write a driver to test the recursive and iterative versions of the function SqrRoot.

SqrRoot(number, approx, tol) = approx, if approx - number tol
