Define a higher order function mult_by that takes one number n as input and returns a function. The returned function takes one parameter x as input, and when called returns the product n*x. Expected Output The following code snippet may be helpful for design and debugging. It illustrates code that creates two functions: one multiplies its input by and the other multiplies it's input by e." import math def main (): if f = mult_by(math.pi) g = mult_by (math.e) print (f (6)) print(g(8)) print (f(10)) print (g(12)) name main() - == __main__":
