Apply a second derivative to identify a critical points as a local maximum, local minimum or saddle point for a function. Find the absolute maximum and minimum of f(33,y) = a: + 3y within the domain 332 + y2 g 1, Please show your answers to at least 4 decimal places. Enter "DNE" if no answer exists. 1. Absolute minimum of f(:13,y) is l: 2. Absolute maximum of f(:;c, y) is l
