Answer:
D(f)=any, R=(-∝;-2].
Explanation:
1) the given graph is quadratic parabola with vertex in point [-2;-2]. If to apply the rules of transformation/moving the graph y=x², then it is possible to make up the equation of the given graph, it is y=-(x+2)²-2;
2) according to the equation y=-(x+2)²-2 the required domain is x∈(-∝;+∝), range is (-∞;-2].
