Please give a clear and complete solution.

Consider the functions f: R² → R² given by f(x, y) = (3y - 5x, x³)
and g: R² → R² given by g(v, w)
=
(-2v², w³+7)
Find the following (make sure to include all of your reasoning- I expect a clear, complete, and detailed solution.):
• Find Df and Dg
• Use the chain rule explained in the course videos to find D(g(f)) at the point (x, y)
=
(2,1).
