Try another version of this question Define the domain of `t(x) = (x+15)/((x-3)(x+8))` . Use interval notation for your answer. The domain of `t(x)` is:
Box 1: Enter your answer using interval notation. Example: [2,5)
Remember we cannot divide by zero. Therefore, the values of `x` that make the denominator of `t(x)` zero are restricted from the domain and are excluded.
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. `(-oo,-8)uu(-8,3)uu(3,oo)`
