I can half-see it, but still can't. I know after that, I can do the conjugate to get the final answer of simplification. But it's from the two functions I couldn't get it. So f(x) gets the 1/sqr(x-1) into it, but what about f(2) ? I don't get that, at all.

Difference Quotient much?
Edit: lol I'll explain hold on
Apply the slope formula to your function f(x) as though it is y(x)
Then... (note below Mikeymoo already has it and is correct)

I don't understand the question....do you not understand how to get from the second to the third line?

sub 2 as x. f(2) is 1/sqrt(2-1) 1/1 1

what?
you plug in 2 for x into the f(x) equation
and the answer is 1
am i missing something here

There's nothing wrong with learning this in, say, 12th grade and getting a bit confused; especially if math isn't your thing.

Ok you are right. The whole point of the blog was to be bm so I really shouldn't complain.
