Question

how to substitute f(x)=1/(x+1) into (f(x+h)-f(x))/h?

I want to make sure I know how to do this. Thanks

Answer 1

tell me what is *f(x+h)* in this case?

Answer 2

that was all the information I was given. it doesn't say what h is in the book.

Answer 3

We don't need to know what h is (in calculus when you start doing this it will "approach" zero, but for now don't worry about this at all)

Answer 4

All I am asking is for the expression for \(f(x+h)\)
