What is the domain of f(x) = cos(x)?
2 answers:
Option D: The set of all real numbers
Explanation:
Given that the function
We need to determine the domain of the function.
The domain of the function is the set of all input values for which the function is real and well defined.
In other words, the domain of the function is the set of all independent x - values of the function.
Thus, the function cos (x) is real and well defined in the interval
Hence, the function cos (x) is real and well defined for all real numbers.
Therefore, the domain of the function is the set of all real numbers.
Hence, Option D is the correct answer.

The midpoint of AB is point G
<h2>Explanation:</h2>The complete question has been attached below. As you can see, we have a line segment which is defined as a part of a line that is bounded by two different points that are at the end of the segment. So here we know that:
- A is located at point -6.
- B is located at point 8
Therefore, the midpoint can be calculated as:
So the midpoint is that matches point G. Finally:
Conclusion: The midpoint of AB is point G
