Question 343682: I need to graph this function. I need the domain, range and horizontal asymptote.
f(x)= 2^x+2
would points (0,4), (1,8), (-1,1) on the graph?

You can put this solution on YOUR website!
If the function is f%28x%29=2%5E%28x%2B2%29, then (0,4) and (1,8) are on the graph. The point (-1,1) is NOT on the graph, but the point (-1,2) is on the graph.


The graph looks like




Now use the graph above to get


Domain: The set of all real numbers.

Range: y%3E0

Horizontal Asymptote: y=0
