(Graph) Sketch a picture of what the function looks like when b is negative and when b is positive.
(Direction) When b > 1 what is the direction of the function? What if 0 < b < 1?
(Concavity) When is the graph concave up? When is it concave down?
(End Behavior) When the function is increasing, what happens to f(x) as x goes to infinity? What happens as x goes to negative infinity?
(Additional Features) Which value of the function represents the y-intercept?
