What is the range of f(x)?
f(x)= 3^(x-2)-1
-------
Determining range::
1. 3 to any power is always positive; so maybe range is >0
2. The -1 pulls all y-values down 1; to maybe range is > -1
---------------
Ans:: Range is All Real Numbers > -1
----------------------
Look at the graph::
graph%28400%2C400%2C-10%2C10%2C-10%2C10%2C3%5E%28x-2%29-1%29
Confirms the range is all >-1.
