a) Find the function, V, in terms of x for the volume of the box.\r
\n" ); document.write( "\n" ); document.write( "\"V+=+%284-2x%29%286-2x%29x\"
\n" ); document.write( "\"V+=+%2824+-20x+%2B+4x%5E2%29x\" Simplify.
\n" ); document.write( "\"V+=+4x%5E3+-+20x%5E2+%2B+24x\" This the function for the volume.
\n" ); document.write( "-----------
\n" ); document.write( "b) The graph of this:
\n" ); document.write( "\"graph%28300%2C200%2C-5%2C5%2C-5%2C10%2C4x%5E3-20x%5E2%2B24x%29\"
\n" ); document.write( "The valid range of x: \"0%3Cx%3C2\"
\n" ); document.write( "--------------
\n" ); document.write( "c) The maximum volume occurs at x = 0.785
\n" ); document.write( "
\n" );
