1.Consider the function: f(x, y) = 2020 + y3-3xy + x3.
a) Find fx(x, y), and fye(x, y).
b) Find all critical points of f(x, y).
c) Classify the critical points of f(x, y) (as local max, local min, saddle).
2.Consider f(x) = 2x-x2and g(x) = x2
a) [2 points] Find the intersection points (if any) of the graphs of f(x) and g(x).
b) [4 points] Graph the functions f(x) and g(x), and shade the region bounded by: f(x),
g(x), x = 0, x = 2.
c) [8 points] Find the area of the shaded region.
