[tex]\int_2^{inf} \frac{2}{(x+3)^{3/2}}[/tex]
integrating the problem, i get:
[tex]\frac{-4}{sqrt(x+3)}[/tex]
now integrating from 2 to inf(replaced with b), plugging in 2, i get -4/5:
f(b) + 4/5
lim->inf
it looks like f(b), lim->inf goes to -4 X 10^-inf
so wouldn't the answer just be divergent? i also tried 4/5 and -4/5, but it wouldn't work. i don't really know the proper way to find the limit. all i do is plug in the largests number and try to find a pattern.
