You can put this solution on YOUR website!
There is an asymptote at x = 9, and x = -8 makes f(x) undefined.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The domain of f(x) is anything that isn't x = -8 or x = 9. You can write this as (-infinity, -8) and (-8, 9) and (9, infinity).
