Explanation:

Step1: Substitute x with -4

To find \( f(-4) \), we substitute \( x = -4 \) into the function \( f(x) = -4x - 5 \). So we get \( f(-4) = -4\times(-4) - 5 \).

Step2: Calculate the expression

First, calculate \( -4\times(-4) = 16 \). Then subtract 5 from 16: \( 16 - 5 = 11 \).

Answer:

11
