a. Define a function max_two(x,y) that accepts as input two numbers, x and y, and returns the larger of the two (or if equal returns either). Use if, elif, and else statements (not the max() function). b. Define a function max_three (x,y,z) that accepts as input three numbers and returns the largest of the three. Try and use max_two0 if possible. c. Define a function min_three(x,y,z) that accepts as input three numbers and returns the smallest of the three. Try and use max_three() if possible.
