**Proposed exercise**

Create a program to display certain values of the function y = x2 - 2x + 1 (using integer numbers for x, ranging from -10 to +10)

**Output**

**Solution**

using System; public class DisplayFunction { public static void Main() { int y, x; Console.WriteLine("y = x² - 2x +1"); Console.WriteLine(); for (x=-10; x <= 10; x++) { y = x*x - 2*x + 1; Console.WriteLine( "x = {0} ; y=({0})² - 2*({0}) +1 = {1}", x, y); } } }
