Problem 4 please

Question 4 Find the second order partial derivatives for the following function: f (2, y) = 9 23y2 + 5 y5 - 3 24 Please input all answers in lower case a and y. Second partial with respect to x : 2- f Second partial with respect to y : 2- f Cross-partial with respect to first x, then y : a2 f day Cross-partial with respect to first y, then ac : 22 f dyx =
