Answer:
y = 1
Step-by-step explanation:
Horizontal Asymptote of a function is the horizontal line that the graph of the function approaches but never touches or crosses.
Horizontal Asymptotes take the form of the equation:
y = a
Where a is a number
Looking at the graph, we see that the function goes closer and closer to the line y = 2 but never will touch/cross.
So, this is the horizontal asymptote's equation: y = 1
