g'(4) is found using the inverse function rule. Given that g(x) = f^(-1)(x), the derivative of the inverse function at x = 4 is (g^(-1))'(4) = 1/3.
The correct answer is (E) 1/3.
Given values:
x: -4, f(x): 0, g(x): -9, f'(x): 5
x: -2, f(x): 4, g(x): -7, f'(x): 4
x: 0, f(x): 6, g(x): -4, f'(x): 2
x: 2, f(x): 7, g(x): -3, f'(x): 1
x: 4, f(x): 10, g(x): -2, f'(x): 3
We are asked to find g'(4), which is the derivative of g(x) at x = 4.
Identify the point where x = 4. At this point, f(x) = 10, and f'(x) = 3.
Since g(x) is the inverse function of f(x), g(10) = 4.
Now, apply the formula g'(x) = 1 / f'(g(x)) and substitute x = 10:
g'(4) = 1 / f'(g(10)) = 1 / f'(4) = 1 / 3
So, the calculation shows that g'(4) = 1/3. The correct answer is (E).
