0.12 and -0.17 I think it's rational, seeing as it's higher than 0, but clarification is appreciated.

I'm not understanding this derivative crap at all, why did they ever make it?

a. Use the definition of the derivative to find f'(x) if f(x) = 4/x when x = 8

b. Find the left and right hand derivatives of f(x) at (1,4) if

f(x) = (x^2 + 3x, x >1) and (x^3 + x^2 + x + 1, x =< 1)


c. Find the equation of a line normal to f(x) if f(-2) = 6 and f'(-2) = 2/3


Thanks guys for all your help!

500= (1.96) (4700/sqrt(n)) This is the answer is n = (1.96)^2 (4700)^2 /(500)^2 =339.44

Why is it that, rather than n = (1.96)^2 (4700)^2 - (500)^2
not sure on the algebra why we divide by 500squared rather than subtracting it.
