Differentiate between abstract class and concrete class.Write a program to create a class named 'Quadratic' that represents a function of the form f(x) = ax + bx +C, where x is a real variable and a, b, c are real constants. The class must satisfy the following requirements: a. A constructor should be provided that takes the values of a, b and c as arguments. All three of these arguments should default to zero. b. A function that takes a single argument x return the value of f(x). c. All data members should be private.[2+8]
