Write a function called "loop_function" that takes two input variables, z and c. The variables z and c are both floating point doubles. When called, the function will perform the calculation: Zn+ = (3.)*-c z +1 repeatedly from n = 0. It will then return the value of n where the magnitude of z becomes greater than 2 (i.e. z 2).
