If y = f (x) has an inverse function and the inverse function of y = f (x + 2) is y = f '(x-1), then the value of F' (1) - f '(0) is () What I did: from the known: F (x + 2) = X-1 Let t = x + 2, x = T-2 f(t)=t-3 f(x)=x-3 f'(x)=x+3 So f '(1) = 4, f' (0) = 3 So f '(1) - f' (0) = 1, why not? The answer is 2

That's right
