The choices are supposed to be
f(x) = sin x + 3
f(x) = cos x + 3 
f(x) = 3 sin x
f(x) = 3 cos x

The amplitude is the value of the numerical coefficient of sin or cos. The only possible answers are
f(x) = 3 sin x
f(x) = 3 cos x

Next, the function must pass through the point (0,3)
3 sin 0 = 0 and
3 cos = 3

Therefore, the answer is
f(x) = 3 cos x

In this exercise we have to identify the function that is addressed in the statement, so we have to:

[tex]f(x)=3cos(x)[/tex]

As we are dealing with a continuous function that is undulating and always passes the values ​​of 0 and 3, we have the following options:

[tex]f(x) = sin x + 3\\f(x) = cos x + 3 \\f(x) = 3 sin x\\f(x) = 3 cos x[/tex]

It was informed about the amplitude in this way recognizing a wave function we only have as options:

[tex]f(x) = 3 sin x\\f(x) = 3 cos x[/tex]

We know that when X=0 the function will be at Y=3, so the only function that does not zero when X=0 is the cosine function.
