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

Answer: B
Step-by-step 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).
