The domain of y = |x| is: (use oo for infinity and -oo for negative infinity)
The range of y = |x| is: (use oo for infinity and -oo for negative infinity)
Enter your answer using interval notation. Example: [2,5) Use U for union to combine intervals. Example: (-oo,2] U [4,oo) Enter each value as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 2^3, 5+4) Enter DNE for an empty set. Use oo to enter Infinity.
