Find the vertex, the line of symmetry and the maximum or minimum value of f(x). Graph the function.
\n" ); document.write( "f(x)=-4(x+8)^2 +2
\n" ); document.write( "**
\n" ); document.write( "Standard for a parabola: y=A(x-h)^2+k, with (h,k) being the (x,y) coordinates of the vertex. A is a multiplier which affects the steepness of the curve.
\n" ); document.write( "For given equation:
\n" ); document.write( "f(x)=-4(x+8)^2 +2
\n" ); document.write( "This is a parabola with the vertex at (-8,2).
\n" ); document.write( "The lead coefficient being negative means the parabola opens downward, and it has a maximum value of 2. The axis of symmetry is y=-8
