The first one is correct and the others I can't really see the picture is blurry
Divide both sides by negative two
the answer is x = -1
The range is the set of values for y. Since y=|x|, y is always positive and increases without bound as x approaches +oo. Thus the range is:
y≥0 which can also be expressed as y=[0, +oo)
