Hi, I am able to answer the question however would just like an extra pair of eyes.

I chose b.

My reasoning being that since derivative is positive, f is positive and so the inverse is positive and increasing, therefore derivative of inverse cannot be d. less than 0.

I can't interpret much else from the answer given for the quiz. Would appreciate any further explanation.

Question 9 Let f be a function. If f' (a) > 2, for any a, which of the following is true? Complete Not graded Select one: Flag O a. f is not invertible. question Ob. dx [f-(x)] 0, for any a, then 1 da [f -1(2)] = F1(f-1 (2)) The correct answer is: d dx [f (2)] , for any a
