Question

Derivative Question, help please!

Answer 1

\[f(x)=\frac{ 1 }{ x+3}\]
To avoid calculating four separate limits, I suggest that you evaluate the derivative at the point when x=a. Once you have the derivative, you can just plug in those four values for "a" to get the answers.

1)f'(-6)=
2)f'(-4)=

Answer 2

i am guessing you are not allowed to use the quotient rule of chain rule and have to do this by hand right?

Answer 3

what is quotient rule?
