You can put this solution on YOUR website!
You are correct. $\"x%3C=-4\"$ or $\"x+%3E+-1\"$ both combine to give you the solution set. To write this in interval notation, you would write\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"(-\infty,$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the parenthesis indicate we exclude the endpoint
\n" ); document.write( "the square bracket means to include the endpoint (we include -4)
\n" ); document.write( "the big U means \"union\" to glue together the two intervals\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To draw out the graph of the solution set on the number line you will have a solid circle at -4 and an open circle at -1. Shade to the left of -4 and shade to the right of -1. Do not shade between -4 and -1. \n" ); document.write( "

\n" );
