I couldn't solve this question, if anyone can explain please

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
