Finding Derivative of f(x) + e^-3x *g(2x+y)

[awesomesauce9596]

Hey guys,

I need to find the derivative of f(x) + e^-3x *g(2x+y). I need to find with respect to x, then with respect to y and then y''.

Thanks!

Okay, so basically I get my wrt x as f'+2e^-3x*g'-3e^-3x*g
I just am confused because I know that g is a function of x and y, so I'm not sure what I have is correct. Also,
I get my wrt y as e^-3x *g' and my y" as e^-3xg".

Just not sure if those are correct or if I am on the right track. Thanks!
