Use limits involving to to describe the asymptotic behavior of the function from its graph. (If the limit is infinite, enter 'co' or '-co', as appropriate. If the limit does not otherwise exist, enter DNE.) f (x ) =. 6x + 1 x - 1 15 10 5 X -10 -5 5 10 -5 - 10/ lim f(x ) X - - 00 lim f(x) = x - 1 f ( x ) x - 1+ lim f(x ) = x - 1' lim f ( x ) = * - 0
