Algebra.Com's Answer #203312 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! For ANY quadratic: \n" ); document.write( "Ax^2 + Bx + C \n" ); document.write( "the axis of symmetry is just: \n" ); document.write( "x = -b/(2a) \n" ); document.write( "(which is from the quadratic equation) \n" ); document.write( ". \n" ); document.write( "Therefore, for your problem: \n" ); document.write( "Find the axis of symmetry for y = x^2 - 9x +3. \n" ); document.write( "b is -9 \n" ); document.write( "a is 1 \n" ); document.write( ". \n" ); document.write( "x = -(-9)/(2*1) \n" ); document.write( "x = 9/2 \n" ); document.write( "It is the vertical line that crosses the x-axis at 9/2. \n" ); document.write( " \n" ); document.write( " |
