Unformatted text preview: we get closer and closer to the yvalue 4, we can say… 4 ) ( lim 2 = → x f x When there is no + or – on the number x is approaching, it means when x approaches the number from BOTH sides. For g(x)… ) ( lim 2 x g x + → does not exist because the yvalues decrease without bound. We do not have a limit for ) ( x g at 2, but we may describe the behavior by looking at each side: We write: ∞ = − → ) ( lim 2 x g x and −∞ = + → ) ( lim 2 x g x ∞ and ∞ are descriptions that tells us why the limit DOES NOT EXIST . This is not an actual limit. We would also say the line x = 2 is a vertical asymptote ....
