Implicit function theorem — which variable can be solved for

Let F:R3→RF:\mathbb{R}^3\to\mathbb{R} be a continuously differentiable function such that F(0,0,0)=−1F(0,0,0)=-1, ∂F∂x(0,0,0)=2\frac{\partial F}{\partial x}(0,0,0)=2, ∂F∂y(0,0,0)=0\frac{\partial F}{\partial y}(0,0,0)=0, and ∂F∂z(0,0,0)=3\frac{\partial F}{\partial z}(0,0,0)=3. For ϵ>0\epsilon>0, define Ωϵ=(−ϵ,ϵ)×(−ϵ,ϵ)⊂R2\Omega_{\epsilon}=(-\epsilon,\epsilon)\times(-\epsilon,\epsilon)\subset\mathbb{R}^2. Which of the following statements are necessarily true?
