Answer 1

just evaluate two integrals with the given domains

Answer 2

\[\int\limits_{0}^{1}5x-3x^2dx+\int\limits_{1}^{2}5x-3dx\]

Answer 3

I got i=6

Answer 4

Outkast, I'd like to point out that second integral isn't supposed to be taken at x=1,
which is why when I answered this, I used
\[\lim_{k\rightarrow 1^+}\int\limits_{k}^{2}5x-3dx\]
