Answer:

So, the domain of \( (f \cdot g)(x) \) would be all real numbers except \( x = -4 \) and \( x = 2 \). Therefore, the correct answer is:

C. {x ∈ ℝ| x ≠ -4, 2}

Step-by-step explanation:

To determine the domain of \( (f \cdot g)(x) \), where \( f(x) \) and \( g(x) \) are two functions, we need to consider the domains of both \( f(x) \) and \( g(x) \) and identify any values of \( x \) where either function is undefined.

Let's suppose \( f(x) \) and \( g(x) \) are defined for all real numbers except for specific values.

If \( f(x) \) is defined for all real numbers except \( x = -4 \) and \( g(x) \) is defined for all real numbers except \( x = 2 \), then the product \( (f \cdot g)(x) \) will be undefined at \( x = -4 \) and \( x = 2 \) because at least one of the functions will be undefined at these points.

So, the domain of \( (f \cdot g)(x) \) would be all real numbers except \( x = -4 \) and \( x = 2 \). Therefore, the correct answer is:

C. {x ∈ ℝ| x ≠ -4, 2}
