Try another version of this question Give the domain of `n(x) = (x^2+4x)/(7-2x)` in interval notation.
Box 1: Enter your answer using interval notation. Example: [2,5)
To find the domain of the function given, identify values of `x` that would make the denominator zero, as these values are not included in the domain.
Use U for union to combine intervals. Example: (-oo,2] U [4,oo)
Enter each value as a reduced fraction (like 5/3, not 10/6) or as an integer (like 4 or -2)
Do not enter mixed numbers
Enter DNE for an empty set. Use oo to enter Infinity. `(-oo,7/2)uu(7/2,oo)`
