Answer:

The amplitude is 3

Explanation:

Given

The right function is:

$y = 3 \cos((1)/(2)x)$

Required

The amplitude

A sine function is represented as:

$y =A \cos(Bx + C) + D$

Where

Amplitude = |A|

By comparing:

$y = 3 \cos((1)/(2)x)$ and
$y =A \cos(Bx + C) + D$

A= 3

So:

Amplitude = |3|

Amplitude = 3

Hence, the amplitude is 3
