the domain is all real numbers because if you graph it, you will see that it covers the whole graph. The range is the y-axis, therefore it is all real numbers greater than or equal ot -2.
The zeroes can be found by setting the equation equal to 0 therefore
abs(X)-2=0
solve for x in which case your zeroes will be x=-2 and x=2
