what is the domain of f(x)= the square root of (x-4) over the set of real numbers?
\n" ); document.write( "**
\n" ); document.write( "Two restrictions apply to the domain: the √(x-4) and the denominator.
\n" ); document.write( "Since there are no variables in the denominator, the only restriction is in the radican:
\n" ); document.write( "x-4≥0
\n" ); document.write( "domain: x≥4
\n" ); document.write( "In other words, the radican cannot be negative \n" ); document.write( "

\n" );
