7-98.

Use the graph at right to find the following limits.

  1.  

    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).

  2.  

    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). 

  3.  

    As , what height does the graph approach?

    Arrow added to left curve, from approximately (negative 5, comma negative 3), down & left. 

  4.  

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

  5.  

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