1. Two of Python’s built-in functions are min and max. In the Python shell, execute the following function calls:

   1. min(2, 3, 4)
   2. max(2, -3, 4, 7, -5)
   3. max(2, -3, min(4, 7), -5)

2. For the following function calls, in what order are the subexpressions evaluated?

   1. min(max(3, 4), abs(-5))
   2. abs(min(4, 6, max(2, 8)))
   3. round(max(5.572, 3.258), abs(-2))

3. Following the function design recipe, define a function that has one parameter, a number, and returns that number tripled.

4. Following the function design recipe, define a function that has two parameters, both of which are numbers, and returns the absolute ...
