See the graph and the explanation.

#y=|x^2-4| >=0# is the combined equation for the pair of parabolas

#y=X^2-4, x ouside [-2, 2] and#

#y=-(x^2-4), x in [-2, 2] .#

Note that Only the parts of the parabolas for #y>=0 are included.

Also, each is the mirror image of the missing part of the other, with

respect to the x-axis.
