Final answer:
The given information is insufficient to calculate (f · g)(2) because it does not specify the functions f and g or provide the necessary details to determine their product at x = 2.
Step-by-step explanation:
To find the value of (f · g)(2) we need to know the specific functions of f(x) and g(x). However, the provided information does not seem to relate directly to the functions f and g, nor does it provide equations or values that can be used to find the product f · g at x = 2. Therefore, without the explicit forms of f and g, we cannot calculate (f · g)(2). The question might be missing some crucial parts or has a typo because the references given discuss topics like lens formula, chemical equilibrium, and projectile motion which are unrelated to the given question about function multiplication. Hence, without the correct information, an accurate answer cannot be provided.
