Compute the limit \( \lim_{x \rightarrow 6} \sqrt[3]{f(x) g(x) - 17} \).

Apply the product law of limits.

Using the given limits, we have \( \lim_{x \rightarrow 6} f(x) = 9 \) and \( \lim_{x \rightarrow 6} g(x) = 9 \). Therefore, \( \lim_{x \rightarrow 6} f(x) g(x) = 9 \cdot 9 = 81 \).

Subtract 17 from the limit of the product.

Now, we compute \( 81 - 17 = 64 \).

Apply the cube root to the result.

Finally, we find \( \sqrt[3]{64} = 4 \).

The limit is \( \boxed{4} \).

The limit \( \lim_{x \rightarrow 6} \sqrt[3]{f(x) g(x) - 17} \) is \( \boxed{4} \).
