You can put this solution on YOUR website!
f(x)=2x-5, g(x)=square root of x+6 (sorry not sure how to do a square root sign)
\n" ); document.write( "Find fog, and then find the domain of fog.
\n" ); document.write( "I got:
\n" ); document.write( "2(square root of x+6)-5
\n" ); document.write( "domain of g=[-6,infinity)
\n" ); document.write( "domain of f=(-infinity,infinity)
\n" ); document.write( "domain of fog=(-infinity,-6]U[-6,infinity)
\n" ); document.write( "--------
\n" ); document.write( "Comment: That union would be All Real Numbers.
\n" ); document.write( "Wouldn't the answer be the intersection rather
\n" ); document.write( "than the union?
