Examine the limit from the left of -1
lim x-->>-1- f(x) = lim x-->-1- (x+1) = -1+1 = 0
Examine the limit from the right of -1
lim x-->>-1+ f(x) = lim x-->-1+ (1-x) = 1-(-1)= 2
SInce lim x-->-1- f(x) is not equal to linm x-->-1+ f(x)
The limit does not exist

Plug -1 one into the second equation because it fits into the rule to that equation. 1-(-1)= 2
