You can put this solution on YOUR website!
Y = 2x^2 + 4x
\n" ); document.write( "A quadratic equation, min occurs on the axis of symmetry which we can find:
\n" ); document.write( "x = -b/(2a), where a=2 and b=4
\n" ); document.write( "x = \"%28-4%29%2F%282%2A2%29\"
\n" ); document.write( "x = -1 is axis of symmetry
\n" ); document.write( "Find y when x=1
\n" ); document.write( "y = 2(-1^2) + 4(-1)
\n" ); document.write( "y = 2 - 4
\n" ); document.write( "y = -2
\n" ); document.write( "coordinates of the turning point -1,-2
\n" ); document.write( "Graphing the equation shows the same thing\r
