Need help in creating a program using calling functions. Instructions shown in picture below, Python only.

Problem 4: Defining and calling functions (25 points) For this problem, you will write three functions, which should obey the rules given in Problem 3. To get full credityour functions should call each other where appropriate to avoid duplicating work. Define a function named increasing that. Takes a list of numbers as a parameter Returns True if each element is greater than or equal to its predecessor, and False otherwise. It should return True if the list has 0 or 1 elements.
