Let f (x, y) = 2x +y. The level curves of the function f are: O A. Straight lines O B. Circles O C. Spheres O D. Parabolas Consider the vector field F(x,y,z) = <4xyz, 2y³ - 3z5, 10ye*> Which of the following statements is CORRECT? Curl F = (10ex-6y²) i- (10yex - 4xy) - 4xz k OF (0,1, -1) is parallel to the vector = (0,2,4) O is conservative. O div F = 4yz + 2y² +10ye*
