Question 2 1 pts Answer the question based on the following snippet of code: def doubler(x): return x*2 def halfer(x): return x/2 def area_of_square(x): return x**2 def my_func(x): areal = area_of_square(x) y = doubler(x) area2 - area of_square(y) return area2 areal my_func(3) How many function calls / invocations are in the above code? O 4 O 5 O 2 O3 Question 13 1 pts What is the most appropriate statement to complete the function body, given that the double function should output the computed value? def double(n): # fruitful function that doubles this number # TODO: print(double(5)) O print("n+n") 0 print(n*2) O return "n*2" return n*2 Question 15 1 pts In what order are these functions called? import math X = int(math.sin(7/pow(2, 3))) O pow, math.sin(), int O math.sin(), int, pow Oint, math.sin(), pow O math.sin(), pow, int
