2-87.
1. For each description below, write a limit equation and sketch a possible function. Homework Help ✎

1. As x → 0, y → 9.

2. As x gets closer to 3 on both sides, f(x) becomes increasingly large.

3. Which of the limits from parts (a) and (b) exist? Explain your reasoning.

Remember, a limit can exist at a hole.

Infinitely large can be notated with the ∞ symbol.

Limits exist if the limit from the left agrees with the limit from the right AND that value is finite.
