Transformation of an Exponential

Comment with words to describe how the changing of the value of a is resulting in a transformation of the orange dotted graph.

ORANGE: f(x)
PURPLE: a•f(x)

1. What kind of function is being graphed by the orange dotted curve?
2. When a is positive, what is the effect of graphing a times f(x)?
3. When a is negative, describe the purple graph as two transformations of the orange graph. Hint, reflect on this for a while.
