(1 point) Consider the ellipsoid 5w2 + y2 l 22 : 30. Find all the points where the tangent plane to this ellipsoid is parallel to the plane 103: + y + 3z : 0. (If there are several points, separate them by commas.) (1 point) Find the point on the graph of z : 7 (23:2 + y?) at which vector 11 : (716, 20, 2) is normal to the tangent plane. P : (1 point) Check that the point (*1, 1, 1) lies on the given surface. Then, viewing the surface as a level surface for a function f(;c, y, z), find a vector normal to the surface and an equation for the tangent plane to the surface at(1,1,1). 2132 e 33/2 + 422 : 3 vector normal = tangent plane: Z
