Answer:
The horizontal line [tex]y=2[/tex] is the asymptote
Step-by-step explanation:
This is an exponential function.
An asymptote is the line a function approaches but never touches.
Here, [tex]y=2[/tex] is the horizontal line that is asymptote of the function.
Note: Normally, y=0 is the asymptote of a parent exponential function, since this graph is parent function shifted 2 units up, the asymptote becomes y=2
