1. The problem statement, all variables and given/known data Assume that the Derivative Rule for Inverses holds. Given that f(x) = x + f(x), and g(t) = f-1(t), which of the following is equivalent to g'(t)? a. g'(t) = 1 + t2 b. g'(t) = 1 + t4 c. g'(t) = 1 + g(x) d. g'(t) = 1 / (1 + t4) 2. Relevant equations 3. The attempt at a solution This question popped up on my recent calc final and my friends and I cannot agree on what the answer is. I answered with C, and most of my friends answered D, arguing that the fraction makes it correct. Can somebody with more knowledge explain this to me? Thank you!
