)evaluating a polynomial limit analytically you should have learned by now the process for finding the derivative of a polynomial (as another polynomial). write a program that will read in from the user a cubic polynomial f(x) (as a set of 4 coefficients), and use this to compute the derivative polynomial (i. e. compute the three coefficients of the derivative f’( then, read in a value for x from a user, and evaluate the derivative polynomial at that x. print out that value. b) evaluating a polynomial derivative numerically
