- (12 points) An even more complex function. Write a function called max 3 that takes as input three numbers, and returns the largest of the three numbers. You may not use the built-in Python functions max or min for this problem. For example, max3 (6, 9, 12) should return 12, and max3 (-7, -7, -42) should return -7. Don't forget a docstring! (6 points) Writing a function. Write a function named weird that takes one input and always returns the number 42 (thus ignoring its input). In this question, include this specific docstring: " This function always returns 42.'' (12 points) A more complex function. Write a function called mypoly that takes as input three numbers (x, y, z), and returns the value of expression x2 + y - 3* z. Don't forget to include a docstring
