You can put this solution on YOUR website!
Yes, it is a POINT with two coordinates, x and y. The value of x is the value of the axis of symmetry, -b/(2a). You get the value of y by substituting that value of x into the parabolic equation of y and solving for y.

\n" ); document.write( "(1) y = x^2 + 4x + 2
\n" ); document.write( "The axis of symmetry is
\n" ); document.write( "(2) x = -b/(2a) or
\n" ); document.write( "(3) x = -4/2 or
\n" ); document.write( "(4) x = -2
\n" ); document.write( "Now put (4) into (1) and get
\n" ); document.write( "(5) y = (-2)^2 + 4*(-2) + 2 or
\n" ); document.write( "(6) y = 4 - 8 + 2 or
\n" ); document.write( "(7) y = -2
\n" ); document.write( "At the point (-2,-2) the parabola reaches a minimum (in this case, because the parabola opens upward).\r
