Question

let f(x) be differentiable on interval A, containing 0.

Answer 1

Let \( x_{n}\) be all sequences in A that converge to 0, but don't equal to 0.
Show if \( f(x_{n}) \) = 0 then \( f'(0)=0 \)

Answer 2

The problem with this question is that I can think of a counter-example:

Answer 3

That is not a counter example

Answer 4

OOF
f(x_n) not equal to 0 here?

Answer 5

correct
