¿Existe  limx2 f(x)\lim_{x\rightarrow2^{ }}\ f\left(x\right)  ?

Si, y es igual a 22  

No porque  limx2 f(x)limx2+ f(x)\lim_{x\rightarrow2^-}\ f\left(x\right)\ne\lim_{x\rightarrow2^+}\ f\left(x\right)  

Si, y es igual a  44

 Señala TODAS las verdaderas limx0 2x+1x2+2x\lim_{x\rightarrow0}\ \frac{2x+1}{x^2+2x}  

 =+=+\infty  

No existe

 limx0 2x+1x2+2x=\lim_{x\rightarrow0^-}\ \frac{2x+1}{x^2+2x}=-\infty  

 limx0+ 2x+1x2+2x=+\lim_{x\rightarrow0^+}\ \frac{2x+1}{x^2+2x}=+\infty  

 limx0 2x+1x2+2x=+\lim_{x\rightarrow0^-}\ \frac{2x+1}{x^2+2x}=+\infty
