Use the definition of the derivative to find f '(x) and f ''(x).
how do i do these?
as h approaches 0 (didnt know the latex for it)
simply plug in x+h for the input for your f(x) function in the part that has (f(x)+h) and simply same with the next which is just the function you were given, now simplify and take/find the limit as it approaches 0 and repeat the process again to get the second derivative
for the first derivative's setup youll have something like
also dy/dx also means first derivative and dy^2/dx means second as well
Hint: simplify top numerator which is in fractions then you'll be dividing a fraction by a fraction which is just like taking the reciprocal of the denominator times the numerator
