The Solution.
The given graph is not the graph of a function, since the graph has two values, ( f(x) = -5 or - 1), at x = -5. So, by vertical test, the graph is not a function.
The second part of the question is the domain and the range.
The domain is an interval, which is,
[tex]-\inftySo,
option B is the correct answer.The range is also an interval, which is
[tex]Range(-\infty,\infty)\text{ or -}\infty
