Well I am not quite sure how to use it to approximate the number ?(6).
You were given the function f(x) = ?(x+5) , a = 4
1st step would be to find f'(x)
f '(X) = 1/2 (x+5)^(-1/2) (1)
= 1/(2?(x+5)
With Linear Approximation
L(x) = Plug "a" into f(x) and f '(x) and solve by adding f(x) f '(x) together
= ?(4+5) + 1/(2?(4+5))
=3 + 1/6 = 18/6 + 1/6 = 19/6
This is what I came up. Hope this helps. I am in no way an expert just a student striving to become a secondary education mathematics teacher. Hope this helps in some way or at the very least point you in the right direction.
