УЛ [10 pts] The figure to the right shows the level curve of f(x, y) = 1 and several gradient vectors of f(x,y) at points along this curve. Draw your estimation for the level curve f(x, y) = 3 and be sure to explain your reasoning for its location and shape. Only the most accurate answer will get full credit. I'll need to see you estimate some necessary values and state some brief written explanations. + х

F(x,y) =-yi + xj. 3 The path C is part of the curve y -Vr from (1,1) to (4,2), with unit tangent vector T and unit normal vector n (take n to have positive j component). The closed path C (with unit tangent vector T and outwardly directed unit normal vector n) extends C by the straight line from (4,2) to (4,0), then along the z-axis to (1,0), followed by the straight line back to (1,1
