You can put this solution on YOUR website!
g(x) is how?
\n" ); document.write( " $\"sqrt%28x%29-1\"$ or $\"sqrt%28x-1%29\"$ ?\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "LATER: You wanted $\"g%28x%29=highlight_green%28sqrt%28x-1%29%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I will do only one of the four examples.
\n" ); document.write( " $\"f%2Ag=f%28x%29%2Ag%28x%29\"$
\n" ); document.write( " $\"%281-3x%5E2%29sqrt%28x-1%29\"$
\n" ); document.write( "and you might leave the function in this form, or 'simplify' to $\"sqrt%28x-1%29-3x%5E2%2Asqrt%28x-1%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "DOMAIN: Obviously if real numbers, the factor needs to be such that $\"x-1\"$ is NOT negative; so $\"x%3E=1\"$ is the domain. \n" ); document.write( "

\n" );
