Based on the sample output provided, and the polynomial.h and task-2.3.cpp files shown below, implement the required member functions and non-member function in your polynomial.cpp file. Write a class Polynomial that stores a polynomial such as p(x) = 5x^10 + 9x^7 - x - 10 as a linked list of terms. A term contains the coefficient and the power of x. For example, you would store p(x) as (5, 10), (9, 7), (-1, 1), (-10, 0) We allow decimal numbers such as4.5 and 6.78 etc to be used as coefficients. Function get_pts (xStart, xEnd, xStepSize): The member function get_pts() calculates and returns a queue of x, y coordinate pairs. They coordinate is calculated from the Polynomial's equation based on the passed parameters of: xStart to xEnd with an increment of xStepSize. Function plot(coords): The non-member function plot() provides a formatted printout of the x, y coordinates returned by the get_pts() function.
