Suppose that f(h)=(8+2h)^1/3

Use the linear approximation to estimate the value of f(h) for small values of h. Give your answer in terms of h.

Thanks for all the help.

(Sorry Bob for not stating the subject last time)

d f(h) = 1/2 ((8+2h)^-2/3 (2)

= (1/f(h))^2

so if f(h) = 10, then for small delta h, the d f(h)= 1/100

Neat.
