Answer 1

To find the domain of the product of the functions \( f(x) = 6x^2 - 2x \) and \( g(x) = 2x \), we first need to consider the domains of each individual function.

1. Domain of \( f(x) \): The function \( f(x) = 6x^2 - 2x \) is a polynomial function, which has a domain of all real numbers, \( \mathbb{R} \).

2. Domain of \( g(x) \): The function \( g(x) = 2x \) is also a polynomial function, which has a domain of all real numbers, \( \mathbb{R} \).

3. Domain of \( (fg)(x) \): The product of two functions, \( (fg)(x) = f(x) \cdot g(x) \), will have a domain that includes all values where both functions are defined. Since both functions \( f(x) \) and \( g(x) \) have a domain of all real numbers, their product \( (fg)(x) \) will also have a domain of all real numbers.

Therefore, the answer is:

• The set of all real numbers.
