Exponential Function

(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?
