Homework Statement
Suppose that f' (2) = 3. Find the limit as x approaches 2 of [f(x)−f(2)]/[sqrt(x) - sqrt(2)]
Answer: 6*sqrt 2
Homework Equations
The Attempt at a Solution
f'(x) = lim h->0 = [f(a +h) - f(a)]/h = slope [f(x)-f(2)]/ x-2
a = 2
i would think that the limit = 3? wrong answer
tried graphing it, but no original function is given
sqrtx and sqrt2 confuses me and not sure how to do it.
thank you
