Java program to evaluate a polynomial function

Determine the end behaviour, y-intercept, average rate of change between two values, instantaneous rate of change (round to two decimals), rational (integer) zeroes, range (all real numbers or having one the form for a polynomial function. Things to remember:  Use methods  In a single program, two parts of a program interact with each other  Check roots, so if user put any value in roots, the program will go back to the main menu and ask the user to put the value in real number.  The program may ask the user some questions in order to determine the answer.  Round the final answer in decimal form.  Something complicated (Advanced level)
