Final answer:
The value of f(-2) for the function f(x) = -3x - 5 - 6x is found by simplifying the function to f(x) = -9x - 5 and substituting x with -2. The calculation yields a result of 13.
Step-by-step explanation:
The question asks to find the value of f(-2) for the function f(x) = -3x - 5 - 6x. First, simplify the function: f(x) = -3x - 6x - 5, which simplifies to f(x) = -9x - 5. Now, substitute x = -2 into the simplified function: f(-2) = -9(-2) - 5. Calculate the value: 18 - 5, which equals 13. Hence, the value of f(-2) is 13, which corresponds to option C.
