For the function , the correct description of the range is y > 0. Here’s a detailed explanation:
Function Analysis
1.Function Definition:
This is an exponential function with base , which is between 0 and 1.
2.Behavior of Exponential Functions with 0 < base < 1:
When the base of an exponential function is between 0 and 1, the function decreases as x increases.
As ,
