You can put this solution on YOUR website!
Remember, (g o f)(x) means g(f(x))\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"g%28x%29=5x-3\" Start with the second function\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"g%28f%28x%29%29=5%284x%5E2+%2B5x%2B7%29-3\" Plug in \"f%28x%29=4x%5E2+%2B5x%2B7\". In other words, replace each x in g(x) with \"4x%5E2+%2B5x%2B7\"\r
