The curve C with equation y=fx passes through the point (3, 14/2)

Question

given that f'(x)=2x+3/xsquared
a) find f(x) (5 marks)
b) verify that f(-2)=5 (1 mark)
c) find an equation for the tangent to C at the point (-2,5) giving your answer in the form ax+by+c=0

Answer 1

f'=(2x+3)/x^2

f'=2/x + 3/x^2
f= int f'= 2lnx -3/x

Answer 2

sorry im really confused, which part of the questions is this answering? can i tell you my answers and you say if they're correct.
a) y=x squared -3x to the power -1 - 1/2

b)i did this :)

c) 13x-4y+6=0
