Solution Steps

Step 1: Substitute the value of \( x \) into the expression

Substitute \( x = -3 \) into the expression \( -x^{2} - 4x - 4 \): \[ -(-3)^{2} - 4(-3) - 4 \]

Step 2: Calculate the exponent

Calculate \( (-3)^{2} \): \[ -(-3)^{2} = -9 \]

Step 3: Multiply and simplify

Multiply \( -4 \) by \( -3 \): \[ -4(-3) = 12 \]

Step 4: Combine the terms

Combine all the terms: \[ -9 + 12 - 4 = -1 \]

The final result is \( -1 \).

Final Answer

\(\boxed{-1}\)

Use the five numbers 12, 11, 16, 17, and 14 to complete parts a) through e) below. Draw a conclusion about the change in the mean. Choose the correct answer below. A. If each piece of data is increased, or decreased, by n, then the mean is multiplied, or divided, by n. B. If each piece of data is increased, or decreased, by n, then the mean is increased by n. That is, adding or subtracting a fixed value to a dataset will both increase the mean. C. If each piece of data is increased, or decreased, by n, then the mean is increased, or decreased, by n. D. The mean remains the same if each piece of data is increased, or decreased, by n.
