Algebra.Com's Answer #528191 by Theo(13342)![]() ![]() You can put this solution on YOUR website! y = x^2 - 3x + 2 \n" ); document.write( "to find the y-axis crossing, make the value of x = to 0 and solve for y \n" ); document.write( "you get: \n" ); document.write( "y = 0^2 - 3*0 + 2 which is equal to 2. \n" ); document.write( "the graph crosses the y-axis as (0,2). \n" ); document.write( "to find the x-axis crossing, you have to set y = 0 and solve the equation. \n" ); document.write( "you get: \n" ); document.write( "0 = x^2 - 3x + 2 \n" ); document.write( "factor this equation to get: \n" ); document.write( "(x-2) * (x-1) = 0 \n" ); document.write( "set each of these factors equal to 0 to get: \n" ); document.write( "x - 2 = 0 \n" ); document.write( "x - 1 = 0 \n" ); document.write( "solve for x in each of these equations to get: \n" ); document.write( "x = 2 \n" ); document.write( "x = 1 \n" ); document.write( "the equation crosses the x-axis at (2,0) and (1,0) \n" ); document.write( "a graph of your equation is shown below:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you can see that it crosses the y-axis at y = 2 and the x-axis as x = 1 and x = 2 \n" ); document.write( "the coordinate points are: \n" ); document.write( "(0,2), (1,0), (2,0)\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
