Use the given sets below to find the new set. Write the simplest version of the resulting set. For example (−∞,5]∪(−2,6) should be written as (−∞,6). Be sure to record your answer using interval notation. If the intersection is empty, type DNE as the answer.
Enter your answer using interval notation. Example: [2.1,5.6172) Use U for union to combine intervals. Example: (-oo,2] U [4,oo) Enter DNE for an empty set. Use oo to enter Infinity.
