i do not understand this question, if someone do it with an explanation. it will be a huge help. i will leave good reviews and comments. Thank you

Find all points (x,y) where f(x,y) has a possible relative maximum or minimum. Then use the second derivative test to determine, if possible, the nature of f(x,y) at each of these points. If the second derivative test is inconclusive, so state. f(x,y) = x3 - y2 -27x + 10y Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The point(s) where f(x,y) has a possible relative maximum or minimum is/are (Type an ordered pair. Use a comma to separate answers as needed.) O B. There is no possible relative maximum or minimum
