Box 1: Select the best answer
Box 2: 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 fraction (like 3/5 or 10/4), an integer (like 4 or -2), or exact decimal (like 0.5 or 1.25)
Enter DNE for an empty set. Use oo to enter Infinity.
Box 3: 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.
