Identify which of the twelve basic functions listed below fit the description given.
-The two functions with infinitely many zeros
A) $y = \sin x , y = \frac { 1 } { x }$
B) $y = \sin x , y = \cos x$
C) $y = \frac { 1 } { x } , y = e ^ { x }$
D) $y = \frac { 1 } { 1 + e ^ { - x } } , y = \operatorname { int } ( x )$

Question

Quizplus · Accepted Answer

The sine and cosine functions both have infinitely many zeros because they are periodic functions with a period of $2\pi$, crossing the x-axis at regular intervals.
