Question

Suppose G(x) = f(u(x)) and each of f and u are differentiable functions. If f (1) = 3, f (3) = −2, f '(1) =1, f '(3) = 4, u(2) =1, u '(2) = −3 , then find G'(2) .

Answer 1

use
\[G'(x)=f'(u(x))u'(x)\] and fill in the numbers

Answer 2

\[G\(2)=f'((u(2))u'(2)=f'(1)\times -3 = 1\times -3=-3\]

Answer 3

you're right...

Answer 4

sweet! that;s what i got. daddy is back in action, rust is peeling away!
