Question

What are the domain and range of f(x) = 2(3x)?

O domain: (-[infinity],[infinity]); range: (0,0)
O domain: (-[infinity],[infinity]); range: (2,[infinity])
O domain: (0,0); range (-[infinity],[infinity])

Answer 1

The domain of f(x) = 2(3x) is all real numbers, and the range is (0, infinity).

Step-by-step explanation:

The domain of the function f(x) = 2(3x) is all real numbers since there are no restrictions on the values that x can take.

The range of the function f(x) = 2(3x) is (0, infinity). To find the range, we can observe that as x increases, 3x also increases, and multiplying by 2 will only make the values larger. Therefore, the range starts from 0 and goes up to positive infinity.
