Give the domain and range of the relation?

The answer is B.

When you are looking for the domain, always look from left to right, the furthest point on the left to the furthest point on the right. And pay attention if the point is shaded or not, if the point is not then it’s > or < without the line on the bottom of it.

When looking for the range, it’s the lowest point to the highest point and pay attention if the graph touches the line, for example: look at y=-2 you will find that the line touches it. If the graphed function doesn’t touch the line then you will have the symbol < or > again but in this situation you the function did touch the line.

The answer would be 7 cages
