Question

What are the domain and range of f(x) = 2(3x)? domain: (negative infinity, infinity); range: (0, infinity) domain: (negative infinity, infinity); range: (2, infinity) domain: (0, infinity); range: (negative infinity, infinity) domain: (2, infinity); range: (negative infinity, infinity)

Answer 1

Answer: its A on edge

Answer 2

The given function is f(x) = 2(3x) = 6x.

The domain of the function is all real numbers since there are no restrictions on the input x. Therefore, the correct answer is:

Domain: (-∞, ∞)

To find the range, we can consider the fact that the function is a linear function with a positive slope of 6. This means that the output values increase as the input values increase.

The lowest possible output value occurs when x = 0, which gives f(0) = 0. As x increases, the output values increase without bound. Therefore, the range of the function is:

Range: (0, ∞)

So, the correct answer is:

Domain: (-∞, ∞)

Range: (0, ∞)
