4.4 Graph Exponential Growth Functions

Vocabulary Exponential Function: y = abx, where a ≠ 0 and the base b is a positive number other than 1. Examples:

Exponential Growth & Decay y = abx

Vocabulary asymptote: line that the graph approaches more and more closely, but does not touch or cross

Vocabulary end behavior of a function’s graph: the y-behavior of the graph as x approaches positive or negative infinity.

Graphing y = bx Graph y = 4x X Y -2 -1 1 2

Graphing y = abx Graph X Y -1 1

Graphing y = abx Graph X Y 1 2

Graphing y = abx-h+k Translates the graph left 2 units down 1 unit

Graphing y = abx-h+k Graph
