Use the graph at right to evaluate each of the following limits. Homework Help ✎
Remember to approach on the curve from both sides of x = 4.
Approach on the curve from the left (− side) of x = 0 only.
As x→∞, what height does the graph approach?
The function must approach the same height from both sides for the limit to exist.
What happens at x = −3?
Does the limit exist here?
