find $\emptyset +\sigma . where \emptyset;R ^3 {\rightarrow}R$ and defined by emptyset(x,y,z)=2x-3y+z and sigma(x,y,z)=4x-2y+3z

where $\sigma;R^3 \rightarrow R$

Would you add the two functions? $$\emptyset +\sigma$$ = (2x-3y+z) + (4x-2y+3z)

6x -5y + 4z

I agree with @jayzdd

Just really convoluted way of saying $$(f+g)(x) = f(x) + g(x)$$.

Also, I am almost positive you mean $$\theta$$ not $$\emptyset$$. The first is Theta, and the second is the emptyset

it seems kind of odd to label a function using the empty set notation. maybe phi
