The results for the matching between function and its period are:
- Option 1 - Letter D
- Option 2 - Letter A
- Option 3 - Letter C
- Option 4 - Letter B
If a given function presents repetitions, you can define the period as the smallest part of this repetition. As an example of periodic functions, you have: sin(x) and cos(x).
The period of sin(x) and cos(x) is 2π.
For solving this question, you should analyze each option to find its period.
1) Option 1
Thus, the option 1 matches with the letter D.
2) Option 2
Thus, the option 2 matches with the letter A.
3) Option 3
Thus, the option 3 matches with the letter C.
4) Option 4
Thus, the option 4 matches with the letter B.
