Identify the domain of the exponential function . which is the graph of f(x)=2^-x? I need to see it graphed please!

Step-by-step explanation:

The domain of any exponential function is "all real numbers."

The value of f(0) is ...

  f(x) = 2^-x

  f(0) = 2^(-0) = 1

Comment on the graph

The free Desmos graphing calculator is an excellent tool for when you "need to see it graphed." It is available in a web browser or as an app for your Android or iOS platform. (I found there to be a little "learning curve", but once you determine the limitations, it is exceptionally useful.) On-line help and tutorials are available, along with some really good examples of use. I can't give you a link, but it is easily found with a search.

the answer to the question is a  

it has the same slope and the same y-intercept.

d? maybe
