Exponential Functions Anatomy

Interact with the app below by dragging the TWO LARGE POINTS. Then answer the questions that follow.
Suppose you graph the [b]exponential function [br][/b][math]y=a^{\left(x-h\right)}+k[/math][br][br]What does the parameter [math]a[/math] do to the graph? How does it affect it? Explain.
Suppose you graph the [b]exponential function [/b][br][math]y=a^{\left(x-h\right)}+k[/math][br][br]How does the parameter [math]h[/math] affect the graph? Explain.
Suppose you graph the [b]exponential function [/b][br][math]y=a^{\left(x-h\right)}+k[/math][br][br]How does the parameter [math]k[/math] affect the graph? Explain.
Does the graph of the [b]exponential function[/b] ever cross [b][color=#a64d79]the dashed horizontal line[/color][/b]? [br][br]Explain how you know it does OR how you know it does not.

What is a Logarithm?

Move the LARGE POINT on the xAxis as far as it will go. You can drag the LARGE POINT that appears behind it anywhere you'd like.
What exactly [i]is[/i] a [b][color=#9900ff]logarithm[/color][/b]? How does/do your observation(s) support your response? Explain.
