$\infty$
We have $$\lim _{x \rightarrow -2^-} \frac{x+1}{x+2}= \infty.$$ We know that the limit from the left will be positive infinity because the numerator and denominator will both be negative, producing a positive overall fraction. The denominator will be arbitrarily close to zero, producing an infinite result.
