Okay, so here are the two functions, f(x)= sqrt(x+3) and g(x) = (x+3)/2(adsbygoogle = window.adsbygoogle || []).push({});

my first step was to get the intersection points and it came out to be x=1 or -3

Then I drew a graph and that told me that the function sqrt(x+3) is always above the other function on the entire interval. So then I did integral f(x)-g(x) dx with upper and lower limits 1 and -3 and the integral gave me (using u substitution as well) 2/3(x+3)^3/2 - 1/4 x^2 +3/2x and then I put in the x values and got 13.3.

Okay so the problem is that the answer in the book is 4/3 and I have no idea where I have gone wrong. Can anyone put me on the right track and tell me where I went wrong
