Consider this very simple function: (15 pts) def cube(x): answer = x * x * x return answer a) what does this function do? b) show how a program could use this function to print the value of y3, assuming y is a variable. c) here is a fragment of a program that uses this function: answer = 4 result = cube(3) print(answer, result) the output from this fragment is 4 27. explain why the output is not 27 27, even though cube seems to change the value of answer to 27.
