If , then how do you derive the density of ? This is what I did: Is this right so far?

The last line is off, you don't want to change the RV X, you want to play with the constant y. You can now differentiate wrt y, and obtain
I got I'm pretty sure this is right, but can someone vouch for me? Thanks.
Did you really add the two densities? AND do note the domain of Y.
Ahh, there's a typo on my original question. If , then am I right? y>0
