Final answer:

After substituting x with -4 in the equation y = x² - 5x - 4, we find that y = 32. This answer is not listed in the provided multiple-choice options, indicating a discrepancy.

Step-by-step explanation:

To determine the value of y when y = x² - 5x - 4 and x = -4, we need to substitute x with -4 in the equation and simplify:

y = (-4)² - 5(-4) - 4

y = 16 + 20 - 4

y = 36 - 4

y = 32

Thus, the value of y is 32, which is not listed in the options provided (A) 24, (B) 12, (C) 0, (D) -24. Hence, there might be a mistake in the provided options or in the calculation itself if we were strictly to choose from the given options.
