You can put this solution on YOUR website!
y = (x+5)^2 + 5
\n" ); document.write( "y = x^2 +10x +25 +5
\n" ); document.write( "y = x^2 +10x +30
\n" ); document.write( ".
\n" ); document.write( "You know this is a parabola. So find several values of x to calculate values of y.
\n" ); document.write( ".
\n" ); document.write( "The axis of symmetry is where x = -b/2a.
\n" ); document.write( "-10/2 = -5
\n" ); document.write( ".
\n" ); document.write( "The vertex is where the parabola ends. It occurs on the axis of symmetry.
\n" ); document.write( "y = (-5)^2 +10(-5) + 30
\n" ); document.write( "y = 25 -50 + 30
\n" ); document.write( "y = 5
\n" ); document.write( ".
\n" ); document.write( "Pick several points to either side of the vertex.
\n" ); document.write( "x = -4, y = 6
\n" ); document.write( "x = -6, y = 6
\n" ); document.write( "x = 0, y = 30
\n" ); document.write( "x = -10, y = 30
\n" ); document.write( "x = 5, y = 105
\n" ); document.write( "x = -15, y = 105
