Best ResponseYou've already chosen the best response.1I'll start you off.......... Given: f(x) = 1/x So, f(a+h) = 1/(a+h) and f(a) = 1/a So the expression you typed above is just: [ (1/(a+h)  1/a] /h When you simplify that complex fraction above (not hard at all), you get 1/[a(a+h)] as your final answer.

Best ResponseYou've already chosen the best response.1Let's take the numerator........ 1/(a+h)  1/a To subtract, you get the LCD which is a(a+h), so 1/(a+h)  1/a = [a(a+h)]/a(a+h) = h/(a(a+h)) Now, the denominator is just h, so you get h/(a(a+h)) divided by h/1 = 1/(a(a+h))
