1. Let f be a function that admits continuous partial second derivatives such that: V{(x, y) = (22 – ar, y? – a) With < 0. It can be assembled with certainty that: A) The point (0, a, f (0, a)) is a chair point of f and f reaches a relative maximum at point (a, a). B) The point (0, a, f (0, a)) is a chair point of f and f reaches a relative minimum at point (a, a). C) The point (a, -a, f (a, -a)) is a chair point of f and f reaches a relative minimum at the point (a, a). D) The point (-a, a, f (-a, a)) is a chair point of f and f reaches a relative maximum at the point (a, a)

1. Let f be a function that admits continuous partial second derivatives such that: V{(x, y) = (2² – ar, y² – a?) With < 0. It can be assembled with certainty that: A) The point (0, a, f (0, a)) is a chair point of f and f reaches a relative maximum at point (a, a). B) The point (0, a, f (0, a)) is a chair point of f and f reaches a relative minimum at point (a, a). C) The point (a, -a, f (a, -a)) is a chair point of f and f reaches a relative minimum at the point (a, a). D) The point (-a, a, f (-a, a)) is a chair point of f and f reaches a relative maximum at the point (a, a)
