How to use linear approximation to estimate $2\ln(1.1)+3$? Can anyone please share how to solve this?
The question is to use the linear approximation to estimate $2\ln(1.1)+3$
The hint given to me was to find f(x) first and find a and f'(a) but I can't follow the hint and don't know how to find those.
Thanks.
I have not tried anything because I am lost at how to find f(x)first or a.
We have only been doing answers where the original f(x) is given then I find the linear approximation and estimate certain values afterwards. This is the first time the f(x) is not provided to me.

Hints:
The tangent to a curve, which is the best linear approximation around the contact point, is the line through the contact point, with a slope equal to the derivative at the contact point.
Use a contact point near $1.1$ that is easy to compute.
