You can put this solution on YOUR website!
h(t) = \"5t%2F%28t-1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "k(t) = \"9%2F%283t%2B7%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(hok)(t) is equal to h(k(t))\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "basically, you are replacing the t in h(t) with k(t)).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you will get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "h(k(t)) = \"%285%2A%289%2F%283t%2B7%29%29%29%2F%289%2F%283t%2B7%29-1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you solve it correctly, you should get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "h(k(t)) = \"45%2F%282-3t%29\"\r
