Use the graph of the function z = -() + 3)(y - 1) below to sketch a graph of solutions to y' = -(y + 3)(y - 1) with initial conditions y(0) = -2 and y(0) = -3.5. You will not turn in your sketch but will use it to answer the following questions. The differential equation y' = -() + 3)(y - 1) has constant solutions. If y(0) = -2, as t increases, y would and would initially be concave The concavity of this solution This solution + If y(0) = -3.5, as t increases, y would and would initially be concave The concavity of this solution This solution
