\(\\\\ \lim_{x \rightarrow -2}\frac{x+2}{|x+2|}\)
\(\text{Como temos uma funcao modular , entao teremos :}\)
\(\\\\ \text{x+2, se x+2\geq 0 \leftrightarrow x\geq-2 }\)
\(\text{e}\)
\(\\\\ \text{-x-2,se x+2<0 \leftrightarrow x<-2}\)
\(\text{entao :}\)
\(\\\\ \lim_{x \rightarrow -2^{+}}\frac{x+2}{x+2}=1\)
\(\text{e temos tbm:}\)
\(\\\\ \lim_{x \rightarrow -2^{-}}\frac{x+2}{-x-2}=-1\)
