Answer
As seen in the graph, it is an odd function and is symmetric about the origin.
Increasing region: $(-\infty,0)$ and $(0,\infty)$
Work Step by Step
Function: $ y=-\frac{1}{x}$
As can be seen from the function and graph, it is an odd function and is symmetric about the origin.
Increasing region: $(-\infty,0)$ and $(0,\infty)$
Decreasing regioin: none
