Question

what is the asymptote? options: x=0, y=1, x=1, y=0

Explanation:

Step1: Recall Asymptote Definition

An asymptote is a line a graph approaches but never touches. For horizontal asymptotes, check the graph's behavior as \( x \to \pm\infty \); for vertical, as \( x \to a \) (vertical line \( x=a \)).

Step2: Analyze the Graph

The graph (exponential - like, maybe \( y = a^x \)) approaches the \( x \)-axis (\( y = 0 \)) as \( x \to -\infty \). It doesn't approach \( x=0 \), \( y=1 \), or \( x=1 \) as an asymptote.

Answer:

\( y = 0 \) (the option "y=0")
