Hey JamesT.
Hint (for Q1): d/dx log(f(x)) = f'(x)/f(x). What is the derivative of SQRT([x+2]/[3-4x])?
I suggest you read the rules of the site. You should not post any more than two questions per thread, and you are expected to be doing your OWN work, this means you show some EFFORT, you post what you have tried and where you are stuck. Then we can give you some guidance. We will NOT do the questions for you.
