Solution

The correct option is C 4
Given : y=||x|22|x|2|
Let us consider curve y=x22x2y=(x1)23

The graph of y=x2 is


Thus, first shifting y=x2 towards right by 1 unit and then moving the graph down by 3 units, we get graph of y=x22x2


Now, graph of y=|x|22|x|2, is


Now, graph of y=||x|22|x|2|, is


As y=||x|22|x|2| and y=1 intersects at four distinct points, hence the number of solutions is 4.
