You can put this solution on YOUR website!
If g(x) varies directly as $\"x%5E2\"$ , then we can write g(x) as:
\n" ); document.write( " $\"g%28x%29+=+kx%5E2\"$ where $\"k\"$ is a constant.
\n" ); document.write( "Given $\"g%285%29+=+50\"$ , we can find $\"k\"$
\n" ); document.write( " $\"50+=+k%285%29%5E2+-%3E+k+=+2\"$
\n" ); document.write( "So the function is $\"g%28x%29+=+2x%5E2\"$
\n" ); document.write( "Here is the graph:
\n" ); document.write( " $\"graph%28300%2C300%2C-10%2C10%2C-30%2C30%2C2%2Ax%5E2%29\"$ \n" ); document.write( "

\n" );
