9-85.

This problem is a checkpoint for evaluating limits from graphs and tables.

  1. Use the piecewise-defined function, , graphed at right to evaluate each of the limits below.

Piecewise graph, line coming from upper left, passing through the point (negative 6, comma 4),  & stopping at the point (negative 5, comma negative 1), increasing curve, opening down, from closed point (negative 5, comma negative 1), to open point (negative 2, comma 3), decreasing curve, opening down, from open point (negative 2, comma 3), to open point (1, comma negative 1), ray from closed point (1, comma negative 3), passing through (6, comma 5), & closed point at (negative 2, comma 2).

  1. Use the piecewise-defined function, graphed at right to evaluate each of the limits below.
