To find \( g(f(x)) \) where \( f(x) = 16x^3 - 7 \) and \( g(x) = 11 - 12x \), we will substitute \( f(x) \) into \( g(x) \).

1. Start by expressing \( g(f(x)) \):
\[
g(f(x)) = g(16x^3 - 7)
\]

2. Now replace \( x \) in \( g(x) \) with \( 16x^3 - 7 \):
\[
g(16x^3 - 7) = 11 - 12(16x^3 - 7)
\]

3. Now simplify \( g(16x^3 - 7) \):
\[
g(16x^3 - 7) = 11 - 12 \cdot 16x^3 + 12 \cdot 7
\]
\[
= 11 - 192x^3 + 84
\]
\[
= 95 - 192x^3
\]

We can now review the available choices to see which one matches \( 95 - 192x^3 \).

None of the choices provided directly match \( 95 - 192x^3 \), but the choice that aligns closely if we consider moving terms around might be:

- **11 − 12(16x³ − 7)**, which directly corresponds with our simplification before breaking it down.

However, ultimately, the actual end result is \( 95 - 192x^3 \), which is the correct representation for \( g(f(x)) \). Thus if you were to express it correctly based on the function outputs, it would be represented as:

**None of the answers exactly match what \( g(f(x)) \) evaluates to**, which is \( 95 - 192x^3 \).

In conclusion, if your options included a direct format or simplified version of \( 95 - 192x^3\), that would be the correct expression for \( g(f(x)) \).
