comment find a CDF for a liner transformation for indipendent random variable
@user107761 note the edit. $F_Y(-1)$ can be simplified, it is really $F_{X_2}(-1)$, and now you just plug in, since you know both $F_{X_1}$ and $F_{X_2}$.

comment Expectation of stochastic differential equation
Assuming $X_0$ is a constant, you end up integrating $$ \mathbb{E}[X_t] = \mathbb{E}\left[ \left(X_0^{1/a} + W_t\right)^a \right] = \int_{-\infty}^\infty \left(X_0^{1/a} + z\right)^a f(z) dz, $$ where $f(z)$ is the pdf of the $\mathcal{N}(0,t)$ distribution.

@EricAm yes, hence the text in the answer "if the limit is $x$"

comment Help proving basic group properties
@Shomar why do you need it? Make 2 cases, inverses of the positives will yield the negative case.
