Someone helllpp me just so o can live in peace. show your work. *loud crying*

F(x) = 2ln(x) + c [integral of 1/x is ln x] 
f(e^(1/2)) = 2ln(e^(1/2)) + c = 5 
2(1/2) + c = 5 [ln(e^a) = a] 
1 + c = 5 
c = 4 

So: 
f(e) = 2ln(e) + 4 = 2 + 4 = 6 

Answer is 6. 

I hope my answer has come to your help. Thank you for posting your question here in .
