To find the value of the function \( y = 18x - 13 \) when \( x = -4 \), we can substitute \(-4\) for \( x \):
\[
y = 18(-4) - 13
\]
Calculating \( 18(-4) \):
\[
18(-4) = -72
\]
Now substituting this back into the equation:
\[
y = -72 - 13
\]
\[
y = -85
\]
The value of the function when \( x = -4 \) is \(-85\), which is not among the listed options.
It's possible that the options provided do not correspond to the equation specified. Could you double-check the options?
