Extracted text: Question 2 Define the function g(x, y) = [4 – (x – 1)²][1 – (y – 2)²]. (a) Find the local maximum point(s) of g, showing the test you used to determine its nature. (b) (i) Determine the linear approximation, g' (x, y), of g near (-2,1). Determine the second-order Taylor approximation, g"(x,y), of g near (-2,1). (You do not need to simplify/expand the approximation formula.) (ii) Estimate the value of g at (-1.9, 1.2) using g" and g'respectively. Compute the error from each approximation and comment on which approximation method is better. (iii) (c) Given that x and y depend on variables u and v according to the parametric equations X = uv y = v – u. ag Determine the partial derivatives and . ди (You do not need to simplify/expand your answer.)
