To solve the problem using Part 1 of the Fundamental Theorem of Calculus, we need to recognize that if \( f(x) = \int_{a(x)}^{b(x)} g(t) \, dt \), then the derivative \( f'(x) \) can be computed as:

\[
f'(x) = g(b(x)) \cdot b'(x) - g(a(x)) \cdot a'(x)
\]

For the given function \( f(x) = \int_{x}^{2} \left(\frac{1}{3} t^3 - 1\right)^9 dt \), observe that:

- \( g(t) = \left(\frac{1}{3} t^3 - 1\right)^9 \)
- \( a(x) = x \)
- \( b(x) = 2 \)

Since \( a(x) = x \) and \( b(x) = 2 \), we can apply the Fundamental Theorem of Calculus as follows:

1. Evaluate \( g(t) \) at the upper and lower limits of integration.
2. Differentiate the limits with respect to \( x \).

Given:
- \( g(t) = \left(\frac{1}{3} t^3 - 1\right)^9 \)
- \( b(x) = 2 \) (so \( b'(x) = 0 \))
- \( a(x) = x \) (so \( a'(x) = 1 \))

Thus:

\[
f'(x) = g(2) \cdot 0 - g(x) \cdot 1
\]

Since \( g(2) \cdot 0 \) is zero, the derivative simplifies to:

\[
f'(x) = -\left(\frac{1}{3} x^3 - 1\right)^9
\]

So, the derivative of \( f(x) \) is:

\[
f'(x) = -\left(\frac{1}{3} x^3 - 1\right)^9
\]
