Give the linearized versions of the nonlinear models in (1) and (2). Write your answers in the form of, for example, y' = '₀ + ' ₁x'₁ + '₂x'₂ + '₃x'₃ + ' , and clearly define the y' , x'_i , '_i and ' in the linearized model in terms of the y, x_i , _i and in the original model.

(1) y = ₀(x₁)^₁ (₂)^x₂ (e^x₃₃ ).

(2) y = x² /(₀+₁x+₂x²+)
