To find the point of intersection, we can graph the function.\r
\n" ); document.write( "\n" ); document.write( "\"graph+%28200%2C+200%2C+-5%2C+4%2C+-5%2C+4%2C+x%2B2%2C+%28-x%29-4%29\"\r
\n" ); document.write( "\n" ); document.write( "
Looking at the graph, the point of intersection is (-1, -3),x=-1 and y=-3\r
\n" ); document.write( "\n" ); document.write( "
f(x) = g(x), f(x)=x+2 and g(x)=-x-4
\n" ); document.write( "-x - 4 = x + 2
\n" ); document.write( "-2x = 6
\n" ); document.write( "x = -3
\n" ); document.write( "

\n" ); document.write( "f(x) = x + 2 , x = -3
\n" ); document.write( "f(x) = -3 + 2
\n" ); document.write( "f(x) = -1\r
\n" ); document.write( "\n" ); document.write( "
or
\n" ); document.write( "g(x) = -x-4, x = -3
\n" ); document.write( "g(x) =-(-3) - 4
\n" ); document.write( "g(x) = 3-4
\n" ); document.write( " = -1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
