Write a script to evaluate a mathematic function f(x, y) for any two user-specified values x and y, where the mathematic function f(x, y) is defined as follows: f(x, y) = { 2x + 2y x 0 and y 0 3x + y^2 x 0 and y < 0 x 2 2y x < 0 and y 0 x^2 + 2y 2x < 0 and y < 0 In the script, prompt the user for x and y values and print the corresponding value of f(x, y) by using if/elseif/else construct. Next, rewrite the problem by using nested if constructs, where the outer construct evaluates the value of x and the inner constructs evaluate the value of y.
