Answer
Not the graph of a function
Domain: $[0, \infty)$
The range is $(-\infty, \infty)$
Work Step by Step
This is not the graph of a function because a vertical line can intersect it in two points which means for each $x$-value there could be more than one $y$-value.
The domain is $[0, \infty)$. The range is $(-\infty, \infty)$.
