    Write a program in java  to evaluate and print the value of the following mathematical function:

    f(x,y) = 2x2 - y + 3

    Vary the values of x and y according to the following table and prints the values of f(x,y) as shown in the table.

    x = ( 3.0,  2.0,  -4.0)

    y = (3.0,  3.0,  2.0)

     

    Thanks

     

    Here’s what I’ve tried

    public class Example {

 

public static void main(String[] args) {

             

              double z;

              double x;

              double y;

             

              z = 2*x*x - y + 3;

             

              x = 3.0;

              y = 3.0;

             

              System.out.println(z);

             

       }

             

             

}

    Hi Mark,

    You can write a separate function and call that function from your main method as below:

     

    public class CalculateFun {

	public static void main(String[] args) {
	    double x = 3.0;
	    double y = 3.0;

	    double z = f(x, y);

	    System.out.println(z);

	}

	private static double f(double x, double y) {
	  return 2 * x * x - y + 3; 
	}
}

     

    Hope this will help you:)
