Use Table 11.1 to find the extreme value(s) of each of the following four functions, and determine whether they are maxima or mìnima: 1. z= x2 + xy +2y² + 3 2. z= -x? - y? + 6x + 2y 3. z = ax² + by² +c; consider each of the three subcases: (0) a > 0, b > 0 (b) a < 0, b < 0 {c) a and b opposite in sign
