Please help me know if I solved this problem correctly Given f(x) = 2x+3, Find E(X) for 0 < x < 2 So the answer is 34/3. Is that correct?

it is true
nope, this does not make sense I have no idea what x- and x+ are. But that is not a valid density $\displaystyle \int_{-\infty}^{\infty}f(x)dx=1$ and $\displaystyle E(X)=\int_{-\infty}^{\infty}xf(x)dx$ where as $\displaystyle \int_0^2(2x+3)dx=10$
