Which of the following is the graph of the equation y = −|−x| ?

Choices are in the attached figure.
Answer (3rd graph = C)



y = −|−x| ..
This means y is ALWAYS negative, irrespective of value of x....
So eliminate all choices that are above x-axis.

second the values will be symmetrical about y-axis..
substitute x as 1 and -1, in both cases y=-1..
for x as 2 or -2, y will be -2

C is the answer
