\fConsider the direction field from the differential equation y' = -y (a) Use the direction field above to sketch the graph of the solution with initial condition y(0) = -1B V A. B. C. D. (b) Are there any equilibria? What are their stabilities? The equilibrium solution y = is asymptotically stableUse Euler's method with step size 0.2 to estimate y(1), where y(a:) is the solution of the initialvalue problem 3/ = 2:1: + :92, y(0) = 1
