Question

I forgot how to take the derivative of a piecewise function! D:

f(x)={ 4-x^2, x< or = 0
-2x, x>0

Answer 1

I need it to find the relative maximum and relative minimum.

Answer 2

To take the derivative of the piecewise function just take it a PIECE at a time.. :)

Answer 3

Hahaha! Awh, what the heck! Thanks!
So,

f'(x)={ -2x, x<or=0
-2, x<0

Answer 4

I don't think the domain restrictions should have changed.

Answer 5

Opps! But, -2, x>0
Would the domain restriction for -2x change? ( -2x, x<0) ?

Answer 6

I don't think so
