Find the limit, if it exist. If the limit does not exist, explain why. 1. lim x->-2 [(2- l x l) /(2+x) l x l = the absolute value of x.

The absolute value here is redundant, since x is not approaching a negative value. Simply plug and chug.
whoops sorry forgot to put -2, its approaching -2.
When x is negative, . Does that help?
