F1 = [ z, y, x ]andF2 = [ z, y, -x ]A. Which of these vector fields is the gradient of a scalar?B. For the vector field that is NOT a gradient, what is theaxis/direction of the curl?C. On your paper, with the axis direction of the curl of the vectorfield that is NOT a gradient, coming perpendicularly OUT of thepaper (which means that the rotation is in the plane of the paper).Draw a few vectors
