Question

What is the amplitude of the graph g(x)=f(x)+2 Where f(x)=cos x

Answer 1

In the cosine equation

`y=AcosB(x-C)+D`

A is the amplitude

B is using it to find the period

C is the phase shift

D is the vertical shift

Since the given function is

`g(x)=cos(x)+2`

A = 1

B = 1

C = 0

D = 2

The amplitude is 1

The answer is 1
