![[image loading]](http://i30.tinypic.com/9qv6n8.jpg) 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.   | ||

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) | ||

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. | ||
