A certain cosine function has an amplitude of 5. Which function rule could model this situation?

a) f(x)=5cos(x)+3f(x)=5cos(x)+3

b) f(x)=3cos(x)+5f(x)=3cos(x)+5

c) f(x)=cos(5x)+3f(x)=cos(5x)+3

d) f(x)=cos(3x)+5

Respuesta :

The answer should be D

The function rule that could model this situation regarding the amplitude is f(x) = 5 cos(x) + 3.

What is an amplitude?

An amplitude simply means a measure of the change in a single period.

It should be noted that the formula of the cosine function will be y = A cos bx

A = Amplitude

Therefore, the function rule that could model this situation regarding the amplitude is f(x) = 5 cos(x) + 3.
