look at the graph: what is the equation of the horizontal asymptote?
Answer
Explanation:
Step1: Identify horizontal - asymptote concept
A horizontal asymptote is a horizontal line that the graph of a function approaches as (x\to\pm\infty).
Step2: Observe the graph
As (x\to\pm\infty), the (y) - value of the graph approaches (y = 0).
Answer:
(y = 0)
