Algebra.Com's Answer #75624 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Find the equation and identify the axis of symmetry, create a suitable table for values, and graph. \n" ); document.write( "y = x^2 - 5x + 3 \n" ); document.write( "---------------- \n" ); document.write( "Table: \n" ); document.write( "If x=0,y=3 \n" ); document.write( "If x=1, y= -1 \n" ); document.write( "If x=2, y = -3 \n" ); document.write( "If x=3, y = -3 \n" ); document.write( "If x=4, y = -1 \n" ); document.write( "etc. \n" ); document.write( "--------------------------- \n" ); document.write( "Put the equation in vertex form by completing the square on the \"x\"-terms. \n" ); document.write( "x^2-5x+? = y-3+? \n" ); document.write( "x^2-5x+(5/2)^2 = y-3+(5/2)^2 \n" ); document.write( "Factor: \n" ); document.write( "(x-(5/2))^2 = y+(13/4) \n" ); document.write( "---------- \n" ); document.write( "This form tells you \n" ); document.write( "Vertex is at ((5/2),(-13/4)) \n" ); document.write( "Axis of symmetry: x = 5/2 \n" ); document.write( "========== \n" ); document.write( " \n" ); document.write( "=========== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
