Answer
See graph.
intercept(s) $(0,0)$.
domain $(-\infty,\infty)$, range $(-\infty,0]$.
Work Step by Step
Step 1. To obtain the graph of $y=-2|x|$ from $y=|x|$, stretch the curve vertically by a factor of 2, then reflect across the x-axis. See graph.
Step 2. We can identify the intercept(s) $(0,0)$.
Step 3. We can find the domain $(-\infty,\infty)$, range $(-\infty,0]$.
