You need to draw parallel lines to x axis and you need to notice if these parallel lines intercepts the graph and y axis in the same time.
You should notice that the parallel line to x axis, that intercepts the end point of the curve, located under x axis, intersects y axis at `y = -4` .
The image shows that the point having the coordinates `x = -2, y = -4` is located on the curve.
Hence, the range of the given function contains all the y values, thus the range is `y >= -4` .
Hence, selecting the accurate answer from the four options provided, yields that d) None of the above, is the valid answer.
I guess image did not go through. Please refer to this graph when answering the question.
