Logarithmic Function

(Graph) Sketch a picture of the graph when b is positive. When b is negative. (Direction) When b > 0 describe the direction of the graph? How about when b < 0? (Concavity) Describe the concavity of the function for b > 0 and b < 0. (End Behavior) When b > 0, what happens to f(x) as x goes to infinity? What happens to f(x) when x goes to 0? When b < 0 describe the end behavior of the function? (Additional Features) Are there restrictions on the value of x? If so what are they?
