I am having trouble with this question: (QUESTION AS ATTACHED)
This is what I tried to do:
I found the intercepts of the difference of the two functions which I found to be only 8.
Then I integrated this into the new function:
[tex]\int{\sqrt{2x}x+4}[/tex]. with limits of 0 and 8 (I don't know how to Latex this)
This, according to my Graphics Calculator yielded 21.3.
However, the answer is 18, what have I done wrong?
Edit: [tex] \int_0^8 (\sqrt{2x} x + 4)\,dx[/tex]
