Question

Help please! Limits problem. attached(:

Answer 1

So did you already do the difference quotient part?

Answer 2

no, i know how to set it up, but I keep getting the wrong answer @myininaya

Answer 3

Are you talking about for the limit part?

Answer 4

f(r)=9r-2/r
\[\frac{f(r+h)-f(r)}{h}\]
Did you get this part?
I'm not asking right now if you evaluated the limit.
But if you did get this part, let me know what you got and we will work from there.

Answer 5

\[\frac{ (9r-\frac{ 2 }{ r } +h) - (9r-\frac{ 2 }{ r } ) }{ h}\]
