Consider the differential equation. A detailed direction field is not needed. Find the solutions that are constant, for all t 20 (the equilibrium solutions). In what regions are solutions increasing? Decreasing? y'(t) =y(y +3)(6 -y) O A. y=0, y= -3, y=6; increasing for - 3 0 O B. y= -3, y=6, increasing for - 3 6 O C. y= -3, y=6; increasing for y 6 O D. y=0, y= -3, y=6; increasing for y6
