Final answer:
The given expression cannot be fully solved without the definition of the function f(x). We can simplify part of the expression but f(-4) is unknown, making it impossible to provide a complete answer.
Step-by-step explanation:
To solve the expression 3 · f(-4) - 3 · 8(-2), we need a function f(x) that gives us the value for f(-4). The information provided does not contain a specific function for f(x), so we must assume that f(-4) represents an unknown value that we cannot determine with the given information.
However, we can simplify the second part of the expression 3 · 8(-2). Using the rule that multiplying two negative numbers results in a positive product, we have:
Without the value of f(-4), we cannot provide a final answer to the expression. Therefore, more information or context is needed to fully resolve this problem.
