Question

Select all true statements regarding limits at infinity.

1. Iim x--> -∞ e^x = 0
2. If lim x --> ∞ f(x) = 9, then a vertical asymptote exists at y = 9
3. Iim x--> -∞ eⁿ = 0, where n is a positive integer
4. the limit of sin(x) as x approaches ∞ does not exist

Answer 1

lim x→- ∞ e^x = 0 and lim x → ∞ sinx DNE
