An investor with risk aversion coefficient $\alpha = 2$ uses modern portfolio theory to describe his preferences over investments. We determine the indifference curve with $U$-value $U(1.1,0.8)$.
$\mu=0.46+\sigma^2$
$\mu=0.46+2\sigma^2$
$\mu=-0.18+2\sigma^2$
$\mu=-0.18+\sigma^2$

Correct: $U(1.1,0.8)=1.1-\frac{1}{2}\cdot 2 \cdot 0.8^2=0.46$.

Hence, $0.46=\mu-\frac{1}{2}\cdot 2 \sigma^2$, which gives $\mu=0.46+\sigma^2$.

Go on.
