CPM Homework Help : A2C Problem 7-112

Below is a graph of $y=\log_bx$ . Describe the possible values for $b$ .
Decreasing curve, opening upward, y axis is a vertical asymptote, and it passes through the point (1, comma 0).

Hint:

Think of the graph of $\log(x)$ . How is this graph different?
How would that affect the equation?
What is the maximum that $b$ could be? What is the minimum?

Use the eTool below to see how different values of b change the graph.
