Write a python program that can be used to find the (�, �) coordinates of the local maxima and the minima points between � = −3 and � = 5 for the polynomial � = �9 − 3�, − 5.5� + 25 (see attached plot). you must evaluate the polynomial by creating a user-defined function to contain it. you may search for minima and maxima using a numpy array or list of (�, �) value pairs. the output should be the coordinates for both the maxima and the minima.

Draw the hierarchy chart and design the logic for a program that calculates service charges for hazel's housecleaning service. the program contains housekeeping, detail loop, and end-of-job modules. the main program declares any needed global variables and constants and calls the other modules. the housekeeping module displays a prompt for and accepts a customer's last name. while the user does not enter for the name, the detail loop accepts the number of bathrooms and the number of other rooms to be cleaned. the service charge is computed as $40 plus $15 for each bathroom and $10 for each of the other rooms. the detail loop also displays the service charge and then prompts the user for the next customer's name. the end-of-job module, which executes after the user enters the sentinel value for the name, displays a message that indicates the program is complete.
