# Find the domain and range of the function. Write your answer in interval notation.8. F(t) = 3 + cos 2t

To determine

To find: The domain and the range of the function.

Explanation

Given:

The function F(t)=3+cos2t.

Definition used:

The domain is the set of all input values of the function for which the function is real and defined.

Calculation:

Recall the fact that the domain of the cosine function is (,) and the range [1,1].

Note that the adding 3 to the cosine function does not change the domain.

Thus, domain of the function F(t)=3+cos2t is (,)
