Answer:

B. 4

Step-by-step explanation:

The given function is of the form:

[tex]f(x) = A \cos(x+C).[/tex]

A is called the amplitude of the given function.

We can read from the graph that, the function ranges between:

-4 and 4

This implies that:

[tex]|A| = 4[/tex]

Therefore the amplitude of the function is 4.

Hence the value of A must be 4.

Answer: it’s 2
