Answer:
- domain: (-∞, ∞) \ (kπ+π/2 for integers k)
- range: (-∞, ∞)
Step-by-step explanation:
The tangent function is undefined at odd multiples of π/2. It can take on any value.
The domain is all real numbers except odd multiples of π/2.
The range is all real numbers.
The answer is: 
The explanation of this exercise is shown below:
1. You have the following expression given in the problem above:

2. By the exponents properties, when you multiply powers with the same base, you must sum the exponents. In this case the base is
, therefore, you must sum the exponents.
3. The result of the sum is 6, therefore,
must be 4:

Answer:
x=-12
Step-by-step explanation:
2/3x=-8
Multiple both sides by 3/2
x=-24/2
x=-12
