Solve the problem.When a function has no stable equilibrium points, many outcomes are possible. One outcome is the stable cycle, in which the points get closer and closer to the cycle, where the values rotate amont a certain number of values. The following value of k leads to a cycle of period 4. Using the logistic function with the given value of k, and starting with  iterate repeatedly until the four x-values in the cycle can be determined to three decimal places.k = 3.50
