The graph of a rational function, f, is shown in the figure. Use the graph to answer the question. 
-Find all horizontal asymptotes of the graph.
A) x = 4, x = -4 
B) x = -6 
C) y = -6 
D) y = 4, y = -4

Quizplus · Accepted Answer

Horizontal asymptotes are of the form y = k, where k is a constant. This means options involving x = k are incorrect, leaving us with options that describe horizontal lines, which are y = k.
