5. $$ \\lim _ { x \\rightarrow - 1 } \\frac { x + 1 } { x ^ { 2 } + 2 x + 2 } $$
Answer
Explanation:
Step1: Substitute (x = - 1) into the function
Substitute (x=-1) into (\frac{x + 1}{x^{2}+2x + 2}). For the numerator: (x + 1=-1 + 1=0). For the denominator: (x^{2}+2x + 2=(-1)^{2}+2\times(-1)+2=1-2 + 2=1).
