On the coordinate plane below, sketch a graph of the antiderivative of f(x) that goes through the point (1, 1) (1, 1) y = f(x),

2. Consider the function f: R²R such that f(x, y) = x²y-2xy² +6xy-3y² +18y +4. (a) Show that f has precisely two stationary points: (-4,-1), and (0,3). (b) Determine the nature of these two stationary points.

8x-5y-3=0 is NOT the correct answer. Please show me the correct answer.
