Calculate values of a function

Calculate values of a function

Monday, November 13, 2023 ⁃ Difficulty: Intermediate

Objective

Create a program Java to display certain values of the function y= x2 - 2x + 1. Ask the user for the range of integers x to show the function.

Instructions

Ask the user for the range of integer numbers x.
Calculate the values of the function (y= x2 - 2x + 1) for each x in the range.
Display the results of the function for each x.

Input

-10
10

Output

121 100 81 64 49 36 25 16 9 4 1 0 1 4 9 16 25 36 49 64 81

Solution

CalculateFunctionValues.java

import java.util.Scanner;

public class CalculateFunctionValues {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.println("Enter the first value of x: ");
        int x1 = scanner.nextInt();

        System.out.println("Enter the second value of x: ");
        int x2 = scanner.nextInt();

        for (int x = x1; x <= x2; x++) {
            int y = x * x - 2 * x + 1;
            System.out.print(y + " ");
        }
    }
}
