Absolute Maximum: Absolute Minimum:A medical student at Brock University is conducting research on a new drug to help patients with Alzheimer's. According to her data, the concentration, in milligrams per cubic centimetres, 1' hours after the injection is given by g(t) : 2t3 + 3Or2 126t + 78 Note: Use interval notation {a,b) U (ml), and for no interval enter 0. The U (union) and (D {empty set) symbols are found in the CalCPad an the right in Sets. (a) The interval where g(t) is increasing is (b) The interval where g(t) is decreasing is (c) The interval where gym is concave up is (d) The interval where g(t) is concave down is
