Explanation:
actually, given the graph, all the answer options are wrong.
the line continues beyond the marked points in both directions. and it connects the marked points. so, there are many more valid x- and y-values between and beyond the points.
in fact, the correct answer for this graph is for domain AND for range to be (-infinity, +infinity).
given the answer choices it is suddenly suggested to consider the marked points only.
domain describes the valid x-values.
range describes the valid y-values.
the marked points have the x-values -3, -2, -1, 0.
and the y- values -4, -2, 0, 2
so, the second answer option seems to be the "correct" answer.
