-Period of $y = - 3 \sin ( 4 \pi x + 2 \pi )$
A) $\frac { 1 } { 2 }$
B) $\frac { \pi } { 2 }$
C) 2
D) $4 \pi$

Question

Quizplus · Accepted Answer

The period of a sine function is given by $ \frac { 2 \pi } { B } $, where $ B $ is the coefficient of $ x $ in the argument of the sine function. Here, $ B = 4 \pi $, so the period is $ \frac { 2 \pi } { 4 \pi } = \frac { 1 } { 2 } $.
