(a) Write a C++ function with the following header double polyval(std::vectorcdouble> coeff, double x) which evaluates any specified real polynomial at a given point. The parameter coeff stores the coefficients of the polynomial from the lowest term to the highest and the parameter x stores the point at which the polynomial is to be evaluated. For instance, the expression polyval({-4,2,7,-8,8,4}, 1.5) evaluates to 58.625, i.e. the value of P(r) = 4r + 8r - 8r+ 7r + 2r I = 1.5 4 at (5 marks) (b) Write a C+ program that allows the user to enter (the coefficients of) a real polynomial and compute the real zero (if it exists and is unique) within a specified interval using the bisection method.
