Enter the amplitude of the function f(x) . f(x)=3/4cos(3x)+4
Alisiya [41]

Answer:

The amplitude is \frac{3}{4}

Step-by-step explanation:

Let f(x) be a sinusoid function that has the following format:

f(x) = bsin(wx + s) + h

Then b is the amplitude of the function

h is the vertical displacement of the wave

s is the phase angle

\frac{2\pi}{w} is the period.

In this problem f (x) = \frac{3}{4}cos(3x) +4

Then \frac{3}{4} = b

Therefore the amplitude of the function is \frac{3}{4}

The amplitude is a measure of the vertical size of the sinx wave
