Decide from the graph whether each limit exists. If a limit exists, estimate its value. (a) lim F(x) (b) lim F(x) x- - 5 X- -6 (a) What is the value of the limit? Select the correct choice below and, if necessary, fill in the answer box within your choice. O A. lim F(x) = x- - 5 (Round to the nearest integer as needed.) y=F(x ) O B. The limit does not exist. X
