Answer:

B: Its range includes all real numbers

Step-by-step explanation:

Ap3x says soB B)

The statement (B) " Its range includes all real numbers." is correct because it does not describe the cosine function.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

The domain of a cos function is al real numbers and the range of the cos function is [-1, 1]

The cos function is the reciprocal of the secant.

The cycle repeats every 21 radians.

Thus, the statement (B) " Its range includes all real numbers." is correct because it does not describe the cosine function.
