Q1: The graphs of y = p(x) are given in below, for some polynomials p(x). Find the number of zeroes of p(x), in each case.

Answer: 

(i) As shown in the graph, it does not intersect x-axis. Hence it has no real zeroes.

(ii) From the graph, it intersects x-axis at one point. ∴ it has one real zero.

(iii) As the graph shows, it intersects x-axis at three points. ∴ the graph polynomial has three real zeroes.

(iv) From the graph, it is clear it intersects x-axis at two points. Hence it has two zeroes.

(v) As the graph shows, it meets x-axis at four points. ∴ it has four real zeroes.

Q1(CBSE 2013):  Define a class Tourist in C++ with the following specifications:
     Data Members:

• CarNo - to store bus number
• Origin - to store Place name
• Destination - to store Place name
• Type - to store Car Type such as 'E' for Economy
• Distance - to store the Distance in Kilometers
• Charge - to store the Car Fare

    Member Functions:

• A constructor function to initialize Type as 'E' and Freight as 250
• A function CalcCharge( ) to calculate Fare as per the following criteria:
  

  Type	Charge
  'E'	16*Distance
  'A'	22*Distance
  'L'	30*Distance

  
  
• A function Enter( ) to allow user to enter values for CarNo, Origin, Destination, Type and Distance. Also this function should call CalcCharge( ) to calculate Fare.
• A function Show( ) to display the content of all the data members on screen.

 Answer:

 const int BUFFSIZE = 40;
 class Tourist
 {
   // private data members
   int carNum;
   char origin[BUFFSIZE];
   char destination[BUFFSIZE];
   char carType;
   int distance;
   int charges;
  public:
    // member functions
    // constructor
   Tourist()
    {
     carType = 'E';
     charges = 250;
    }

   // calculate charges
   void CalcCharges()
    {
     if (Type == 'E')
     {
      charges = 16*distance;
     }
    else if (Type == 'A')
     {
      charges = 22*distance;
     }
    else if (Type == 'C')
     {
      charges = 30*distance;
     }
 };

 // enter values
 void Tourist::Enter()
 {
   cout << "Enter CarNo, Origin, Destination, Type, Distance:";
   cin >> carNum;
   gets(origin);
   gets(destination);
   cin >> carType >> Distance;
   CalcCharges();
 }
 
 // show/display details
 void Show()
 {
   cout << "Car No: " << carNum 
        << "\nOrigin: " << origing 
        << "\nDestination: " << destination
        << "\nType: " << carType
        << "\nDistance: " << distance
        << "\nCharges: " << charges << endl; 
 }
 };

Polynomials

Study Points

1. An expression of the form a₀ + a₁x + a₂x² + ----- + a_nxⁿ where a_n is called a polynomial in variable x of degree n. where; a₀ ,a₁, ----- a_n are real numbers and are called terms/co-efficients of the polynomial and each power of x is a non negative integer.

2. Polynomials in the variable x are denoted by f(x), g(x), h(x) etc.
    e.g. f(x) = a₀ + a₁x + a₂x² + ----- + a_nxⁿ

3. A polynomial p(x) = a (where a is constant) is of degree 0 and is called a constant polynomial.

4. A polynomial p(x) = ax + b is of degree 1 and is called a linear polynomial. e.g. 4x - 3, 5x...

5. A polynomial p(x) = ax² + bx + c of degree 2 and is called a quadratic polynomial.
    e.g. 3x² -x + 5, 1- x²...

6. A polynomial p(x) = ax³ + bx² + cx + d of degree 3 and is called a cubic polynomial.
    e.g. √5x³ - 2x² + 5x -1...
