Show that the linearization of f(x) = (1+x)k at x = 0 is L(x) = 1 + kx.
O
If f is differentiable x = a at then the approximating function L(x) = f(a) + f'(a)(x-a) is the linearization of f at a. Determine f(0).
f(0) = (Simplify your answer.)
Determine f'(x).
O A. f'(x) = (1+x)k
OB. f'(x)=k(1+x)k-1
OC. f'(x)=(1+x)k-1
OD. f'(x)=k(1+x)k
Determine f'(0).
f'(0) =
Using the values of f(0) and f'(0) found in the previous steps, determine the linearization L(x) = f(a) + f'(a)(x-a) for a = 0.
OA. ) = f(0) + f'(0)(x 0+k(x-0) = 1+kx
O B. L(x)=f(0) + f'(0)(x- 0) = 1+k(x-0)=1+kx
OC. L(x) = f(0) + f'(0)(x-0) = 1 +x+k(0) = 1+kx
OD. L(x)=f(0) + f'(0)(x-0)=k+1(x-0) = 1+kx
