a simple plotting question

How do I plot the following function of two variables? (not 3-d plot!)

g[y_]=y^3;
h[z_]=z^2+8

f[y_,z_]=g[y]+h[z]

Plot[f[y,z],{y+z,0,3}]?? or

Plot[f[y,z],{x,0,y+z}]??

I mean the x-axis is devided into two parts, so x is y and z dependent, so how do I plot it?

Thanks a lot
