This is one of the simplier questions. As I´m so bad at Derivating numbers I have to ask this. What is f´(3) if F(x)=2x^2? As far as I understand it it should be something like: (f´3=f (2+h) - f(3))/h I get it to 12+2h^2, is that correct? The fact checker (in the end of the book says that the answer is 3 though, it seems they get it wrong sometimes).

This is one of the simplier questions. As I´m so bad at Derivating numbers I have to ask this.
What is f´(3) if F(x)=2x^2?
As far as I understand it it should be something like: (f´3=f (2+h) - f(3))/h
I get it to 12+2h^2, is that correct? The fact checker (in the end of the book says that the answer is 3 though, it seems they get it wrong sometimes).
