comment Showing it is a joint probability density function
read wikipedia please. $F_x$ is the integral of $f_x$. can you obtain $f_x$ and $f_y$ first?

comment Showing it is a joint probability density function
you can use the double integral it is simple and will give you $1$. Since your function is continuous and positive, then you can conclude that it is indeed a density

I think this problem makes sense in case the flipping action has some density function.
