To calculate \( f(5) \) for the function \( f(x) = -4x - 5 \), we substitute \( x = 5 \) into the function:
\[
f(5) = -4(5) - 5
\]
Calculating this step-by-step:
1. \( -4(5) = -20 \)
2. \( -20 - 5 = -25 \)
So, \( f(5) = -25 \).
Now, let's examine the options you provided to see if \( (5, -25) \) matches any of them:
- (5, 6)
- (8, 9)
- (2, 3)
- (6, 7)
None of these pairs match \( (5, -25) \). It seems that there may be a misunderstanding or error in the options provided, as none correspond to the calculated value of \( f(5) \).
