The x-coordinate of the vertex of $\"f%28x%29+=+3x%5E2\"$ is:
\n" ); document.write( " $\"x+=+-b%2F2a\"$
\n" ); document.write( "In this function: $\"f%28x%29+=+3x%5E2\"$ , a = 1 and b = 0, so the x-coordinate is...
\n" ); document.write( " $\"x+=+-0%2F2%281%29\"$
\n" ); document.write( " $\"x+=+0\"$ and, when x = 0, then f(0) = 0, so he ordered pair of the vertex is:
\n" ); document.write( "(0, 0) and the equation of the line of symmetry is:
\n" ); document.write( " $\"x+=+0\"$ which is just the y-axis.
\n" ); document.write( " $\"graph%28400%2C400%2C-5%2C5%2C-5%2C5%2C3x%5E2%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
