## anonymous 4 years ago Find the derivative of f(x)=−11x−12

1. anonymous

do you know how to use first principle?

-11

$f'(x)= \frac{d}{dx}(-11x) - \frac{d}{dx} (-12)$ $=-11$

kindly guys. don't solve complete. let a person to do it by his/her self.

5. anonymous

just give a hint and we are here available for help 24/7

Note: $\frac{d}{dx} c = 0$ where c is constant

=D

and $\frac{d}{dx} x =1$

$\ \frac{d}{dx} (-11x) =-11 \frac{d}{dx}x =-11(1)= -11$
