All the functions that are not pure are impure. This makes the definition of an impure function as "A function that is dependent on i/o or other values out of function's scope along with parameter values."Now, let's create an impure function:...
Step 1: Determine the Domain of Definition D D = R* = R – {0}Step 2: There is no Periodicity and Symmetry of f E = D = R*[See Note below for Periodic and Symmetric example]Step 3: Continuity of f The function f is the quotient of 2 polynomial functions, therefore f is ...
