Hi,
\n" ); document.write( "As for the domain, you are being asked:
\n" ); document.write( "\" What values of $\"+x+\"$ are possible? \"
\n" ); document.write( "You can plug any value of $\"+x+\"$ into the
\n" ); document.write( "equation, either positive, negative, or zero,
\n" ); document.write( "and the function, which is $\"+x%5E2+-+5+\"$
\n" ); document.write( "will return some number.
\n" ); document.write( "So, the domain is minus infinity to plus infinity
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "As for the range, you are being asked:
\n" ); document.write( "\" What values of the function $\"+x%5E2+-+5+\"$
\n" ); document.write( "are possible? \"
\n" ); document.write( "This function can be as large a positive number
\n" ); document.write( "as you want- just keep making $\"+x+\"$ more positive, or
\n" ); document.write( "you can keep making $\"+x+\"$ more and more negative
\n" ); document.write( "and the function gets more positive.
\n" ); document.write( "Also the function can be zero. Just make $\"+x+=+sqrt%285%29+\"$ , or
\n" ); document.write( " $\"+-sqrt%285%29+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "But the function $\"+x%5E2+-+5+\"$ can only be as negative as $\"+-5+\"$
\n" ); document.write( "There is nothing you can do to the $\"+x%5E2+\"$ term to make
\n" ); document.write( "the function more negative than $\"+-5+\"$
\n" ); document.write( "--------------------
\n" ); document.write( "So, the range of $\"+x%5E2+-+5+\"$ is $\"+-5+\"$ to plus infinity
\n" ); document.write( "Hope this helps\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
