Question

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

Answer 1

Answer:

The amplitude is 1

Step-by-step explanation:

Given

The right function is:

$y = \cos(5x + \frac{2}{5}\pi) +5$

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 $y = \cos(5x + \frac{2}{5}\pi) +5$

$A = 1$

So:

$Amplitude = |1|$

So, we have:

$Amplitude = 1$
