This is the vector analysis hw problem about jacobian

s. (a) (1 point) [ ]" - adoc [ a 6 ] when ad - bc # 0 O True False (b) (3 points) Given g: R - R' from the previous problem, consider the implicit function f : Ns((1, 1)) - R2 of the form f(x, y) = (u(x, y), v(x, y)) such that f (1, 1) = (2, 1) and g(x, y, u(x, y), v(x, y)) = (0,0) V(x,y) E Ns((1, 1)). Use implicit differentiation to find the Jacobian of f at (x, y) = (1, 1). (c) (2 point) Take h(x, y) = (x + y, y). Compute the Jacobian of h at (r, y) = (1, 1)
