Use the graph at right to find the following limits.

Remember to approach on the curve from both sides of

. What height is that?Arrows added to right curve, left pointing up & right, left of open point (4, comma 4), & right pointing up & left, right of open point (4, comma 4).

Approach on the curve from the left (− side) of

only.

What height is that?Arrow added to center curve, from the point (negative 2, comma 0), to open point (0, comma negative 2).

As

, what height does the graph approach? Arrow added to left curve, from approximately (negative 5, comma negative 3), down & left.

You must approach the same height from both sides for the limit to exist.

Arrows added to left curve, left pointing up & right, left of dashed line, & right pointing up & left, right of dashed line.
