## Pawanyadav one year ago If g is the inverse of a function f and f'(x)=1/(1+x^5), then g'(x)=? A)1/(1+{g(x)}^5) B)1+{g(x)}^5 C)1+x^5 D)5x^4

do you know if m and n are inverse functions then $m'(x)=\frac{1}{n'(m(x))}$

Yes

3. freckles

well that is what I would use

Where you use it?

5. freckles

$g'(x)=\frac{1}{f'(g(x))}$

6. freckles

this is just a pluggin kind of problem you don't even have to find the derivative

7. freckles

or I mean you don't have to differentiate

8. freckles

you do have to find g'(x) but not differentiating needed
