SOLUTION
We want to find the domain, range and asymptote of
[tex]y=3^{-x}+1[/tex]
The graph of this function is shown below
From the graph above
Domain: The domain is determined from the x-axis or x-values. From the graph, we can see that the graph if it continues to expand, it can accommodate an ifinitely number of x-values. Also any value of x imputed makes the function defined. Hence the answer is all real numbers
In interval notation Domain is
[tex](-\infty,\infty)[/tex]
Range is the y-values. From the graph, the y-values starts from 1 and go above.
In interval notation, range becomes
[tex]undefined[/tex]
