A horizontal line that a graph approaches as inputs grow without bound is a horizontal:
AAlignment
BAsymptote
CAmplitude
DAssembly
Answer & Solution
Correct answer: B. Asymptote
1. Far out to the left and right the outputs settle.
2. They level off towards one fixed height.
3. That line is a horizontal asymptote.
