Step 1 :Find the value of f(3) from the table: f(3) = 2
Step 2 :Find the value of f'(3) from the table: f'(3) = 7
Step 3 :Find the value of g(3) from the table: g(3) = 6
Step 4 :Use the formula g'(x) = 1 / f'(g(x))
Step 5 :Substitute g(3) = 6 and f'(3) = 7 into the formula: g'(3) = 1 / f'(g(3)) = 1 / f'(6) = 1 / 6
Step 6 :The value of g'(3) is \(\boxed{\frac{1}{6}}\)
