Answer

Explanation:

Step1: Apply the quotient rule

The quotient rule states that if (y = \frac{u}{v}), then (y'=\frac{u'v - uv'}{v^{2}}). Here, (u = xf(x)) and (v = g(x)). First, find (u') using the product rule. The product rule: if (u=xf(x)), then (u'=f(x)+xf'(x)).

Step2: Substitute (x = 2)

When (x = 2), (f(2)=3), (f'(2)=6), and assume (g(2)) and (g'(2)) values (since the table for (g(x)) and (g'(x)) is not given, but from part (a) we assume the problem has all - necessary data. Wait, no, looking at the table: the first row (x:2,3,4,6,9), second row (f(x):3,2,9,6,4), third row (f'(x):6,9,4,2,3). Maybe there is a mis - take in the problem statement, but assuming (g(x)) and (g'(x)) follow the same (x) values. Let's re - check: The formula for (\frac{d}{dx}\left(\frac{xf(x)}{g(x)}\right)) at (x = 2) is (\frac{(f(x)+xf'(x))g(x)-xf(x)g'(x)}{g^{2}(x)}) Substitute (x = 2): (f(2) = 3), (f'(2)=6), assume (g(2)) and (g'(2)) (if we assume (g(x)) and (g'(x)) have the same (x) mapping as (f(x)) and (f'(x)) in the table. Wait, no, the problem is incomplete. But if we assume (g(x)) and (g'(x)) are the same as (f(x)) and (f'(x)) (a wrong assumption, but for the sake of using the given data): (\frac{(3 + 2\times6)\times3-2\times3\times6}{3^{2}}=\frac{(3 + 12)\times3-36}{9}=\frac{15\times3-36}{9}=\frac{45 - 36}{9}=1)
