To find the value of the function \( y = 18x - 13 \) when \( x = -4 \), we can substitute \(-4\) for \(x\) in the equation.
\[ y = 18(-4) - 13 \]
Calculating \( 18 \times -4 \):
\[ y = -72 - 13 \]
Now, combine the constants:
\[ y = -72 - 13 = -85 \]
Since none of the provided responses match \(-85\), please double-check the function or the value of \(x\) given in the question.
