alright there is this question which uses NR method to find intersect but i kept getting the wrong ans can anybody help me check which part i went wrong?(adsbygoogle = window.adsbygoogle || []).push({});

f(x)=2x + ln4x , f'(x)=2+ 1/x

btw,differentiate ln4x and lnx get the same result but the arbitary constant is different right?so do we consider the constant when finding the intersect?
