$\text{a) increasing: } \text{none} \\\text{b) decreasing: } (-\infty,\infty) \\\text{c) constant: } \text{none}$

Work Step by Step

From the $x-$interval of $ ( -\infty, 0 ] $ the graph goes down. From the $x-$interval of $ [0,\infty) $, the graph goes down. Hence, the graph has the following characteristics at these intervals: \begin{array}{l}\require{cancel} \text{a) increasing: } \text{none} \\\text{b) decreasing: } (-\infty,\infty) \\\text{c) constant: } \text{none} .\end{array}
