Logistic Function

(Graph) Sketch the graph of the function when B > 0 and when B < 0. (Direction) Describe the direction of the function when B > 0 and when B < 0. (Concavity) Describe the direction of the function when B > 0 and when B < 0. (End Behavior) For B > 0, when x goes to negative infinity, what happens to f(x)? What happens to f(x) as x goes to infinity? (Additional Features) L is the limiting value of the function.
