For questions 2 what does the last line of the given equations mean? The part is $u|_{x=+0}=\alpha u|_{x=-0}$  and $u_x|_{x=+0}=\beta u_x|_{x=-0}$. I don't know what this means or how to solve it with those parameters.

For question ten, I get the general solution, but I am unable to find the function given by the IVP.
I get $\phi(-\frac{x^2}{2}-x)=f(x)$.
