can someone show me how this is done.. the lnx function has me a bit confuse

lnx = 4-x

starting with 2.9 as s first approximation to this roots use newton-rapson method to evaluate successive approximations to this root to 2 decimal places.

We want to find the solution to...

where .

We also have,

Newtons Method (aka Newton-Rapson Method) is

Which for our problem is...

So we get...

Etc...

I'll leave it to you to compute each
