Graphing Exponential Functions
Learning Objective
I can graph exponential functions and identify their key features.
Key Concepts
The initial value of the exponential function h(x) = 27 * (1/3)^x is 27, which is the value of h(x) when x equals 0.
To graph the exponential function, you can define two points and a horizontal asymptote.
As x becomes very large, the function h(x) = 27 * (1/3)^x approaches 0, indicating a horizontal asymptote at y = 0.
