You can put this solution on YOUR website!
Alright, some other tutor correct me in I am wrong, but I believe I can do this:\r
\n" ); document.write( "\n" ); document.write( "To find f(f) we replace f (x+1) with all of the x's in the f (x+1) equation:\r
\n" ); document.write( "\n" ); document.write( "x+1+1\r
\n" ); document.write( "\n" ); document.write( "we get x+2 is your f(f)\r
\n" ); document.write( "\n" ); document.write( "Do get the domain, we set the denominator of the fraction to 0\r
\n" ); document.write( "\n" ); document.write( "[-1]+1=0\r
\n" ); document.write( "\n" ); document.write( "The domain in interval notation is (-infinity,-1) union (-1, infinity)\r
\n" ); document.write( "\n" ); document.write( "The range, you set the numberator to 0\r
\n" ); document.write( "\n" ); document.write( "[1]-1=0\r
\n" ); document.write( "\n" ); document.write( "The range in interval notation is (-infinity,1) union (1, infinity)\r
\n" ); document.write( "\n" ); document.write( "Hope this helps!\r
