You can put this solution on YOUR website!
You want an input of x instead of input of 2x-1. Maybe the inverse of 2x-1 will be that input x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"L%28x%29=2x-1\"
\n" ); document.write( "\"L%5E-1%28x%29\" should be inverse of L.
\n" ); document.write( "\"2%2AL%5E%28-1%29-1=x\"
\n" ); document.write( "\"2%2AL%5E%28-1%29=x%2B1\"
\n" ); document.write( "\"L%5E%28-1%29=%28x%2B1%29%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You want to form \"f%28L%28L%5E%28-1%29%28x%29%29%29\"
\n" ); document.write( "-
\n" ); document.write( "This should be f(x): \"8%28%28x%2B1%29%2F2%29%5E3+-+12%28%28x%2B1%29%2F2%29%5E2+%2B+4%28x%2B1%29%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x%2B1%29%5E3-3%28x%2B1%29%5E2%2B2%28x%2B1%29\"
\n" ); document.write( "which is still much in unsimplified form.
\n" ); document.write( "You can do what you need or want with it, but that should be equivalent to f(x).
\n" ); document.write( "
\n" );
