Hi I need to graph the following quadratic equations:\r \n" ); document.write( "\n" ); document.write( "y=x^2+2x+5 \n" ); document.write( "-------- \n" ); document.write( "The low point where x = -b/(2a) = -2/(2) = -1 \n" ); document.write( "------ \n" ); document.write( "f(-1) = 1-2+5 = 4 giving you the low point (-1,4) \n" ); document.write( "f(0) = 0+0+5 = 5 giving you the point (0,5) \n" ); document.write( "f(-2) is symetric so have the point (-2,5) \n" ); document.write( "--- \n" ); document.write( "Plot those points and draw a parabola thru them:: \n" ); document.write( " \n" ); document.write( "---------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "--------------- \n" ); document.write( "------ \n" ); document.write( " \n" ); document.write( " |
