The domain of a function are all ALLOWABLE values of x.
\n" ); document.write( "The range of a function are all POSSIBLE values of y.
\n" ); document.write( "For y = x^2 + 3, the lowest value y can ever have is when x = 0. That would be 3.
\n" ); document.write( "Thus the range of the function is y >= 3, or [3, infinity).
\n" ); document.write( "
\n" );
