Question

Determine the amplitude or period as requested. Amplitude of y = cos 5x a (2pi)/5 b 1 d 5

Answer 1

The amplitude is 1

Explanation:

Given

The right function is:

`y = \cos(5x + (2)/(5)\pi) +5`

Required

Determine the amplitude

The general cosine function is:

`y = A\cos(k(x + c)) +d`

Where

`Amplitude = |A|`

Compare
`y = A\cos(k(x + c)) +d` and
`y = \cos(5x + (2)/(5)\pi) +5`

`A = 1`

So:

`Amplitude = |1|`

So, we have:

`Amplitude = 1`
