Answer
a. See the graph
b. Domain: $(-\infty,0)\cup (0,\infty)$; Range $[-1,1]$
c. No.
Work Step by Step
a. See the graph above.
b. The domain of any function consists of the values it can take on the x-axis, whereas the range consists of the value it can take on the y-axis. These values can be confirmed by graphing the function.
Domain: $(-\infty,0)\cup (0,\infty)$; Range $[-1,1]$
c. No, this function is not periodic. It oscillates with increasing frequency near the origin and no constant period exists.
