Answer :
Absolute value graphs always look like the letter V .They can open up or down.
Domain is set of values x can take .For any absolute value function x can take any value .We can say
The domain of the function is
C) (-∞,∞)
If the graph opens downward, the range will be less than or equal to the y-coordinate of the vertex. The y coordinate is 0 so Range will be less than 0.
The range of the function is
B) (-∞,0]
