Final answer:
The equation to find the horizontal asymptote for the function eˣ is y = 0.
Step-by-step explanation:
The equation to find the horizontal asymptote for the function eˣ is y = 0.
When a function approaches a horizontal asymptote, it means that the function's output approaches a constant value as the input increases or decreases without bound. For the function eˣ, the graph approaches the x-axis, which is the horizontal line y = 0.
For example, as x approaches positive infinity, eˣ approaches 0.
