Question

ANYONE GOOD WITH CALCULUS?! PLEASE HELP ME!!! Use the antiderivative formula shown, where f(u) represents a function. Which function represents f(u)?

Answer 1

Answer: B

Explanation:

For this problem, we can use Integration by Parts to find f(u).

∫(ln u) du x=ln u dx=1/u du

dv=du v=u

u(ln u)-∫u(1/u)du

u(ln u)-∫1 du

u(ln u)-u+C

Looking at the placement of f(u), we know that f(u) is u (underlined above).
