La funzione

 y=f(x)y=f\left(x\right)  ha un asintoto orizzontale di equazione  y=2y=-2  raggiunto da sotto per x che tende a  ++\infty  . Quali delle seguenti scritture è coerente con tale informazione?

 limx2 f(x)=+\lim_{x\rightarrow-2}\ f\left(x\right)=+\infty  

 limx2f(x)=+\lim_{x\rightarrow-2^-}f\left(x\right)=+\infty  

 limx+ f(x)=2\lim_{x\rightarrow+\infty}\ f\left(x\right)=-2  

 limx+f(x)=2\lim_{x\rightarrow+\infty}f\left(x\right)=-2^-  

 limx f(x)=2\lim_{x\rightarrow\infty}\ f\left(x\right)=-2
