Question

If f(x) = ln(1 − 2x), then find f '(x).

Answer 1

f(x)=ln(1-2x) this is complex function

f'(x)=1/(1-2x)*(1-2x)'= 1/(1-2x)*(-2)=-2/(1-2x)= 2/2x-1

Good luck!!!

Answer 2

`f'(x) = -(2)/(1-2\cdot x)` for
`x < (1)/(2)`

Explanation:

The function is derived by chain rule:

`f'(x) = -(2)/(1-2\cdot x)`, for
`x < (1)/(2)`
