-$y = 5 \sin \frac { 1 } { 4 } x \quad$ Find the amplitude.
A) 2
B) $6 \pi$
C) $\frac { \pi } { 2 }$
D) $\frac { 2 \pi } { 3 }$

Question

Quizplus · Accepted Answer

The amplitude of a sine function $y = a \sin(bx)$ is given by the absolute value of $a$, which in this case is $|5| = 5$. However, none of the provided options includes 5, indicating a possible mistake in the question or answer choices. Given the options, none directly match the correct amplitude of 5.
