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.

<h3>Given:</h3>
- Trapezium
- Length of BC
- Value of "x"
We can divide the given shape into a triangle and a rectangle.
We'll have to use Pythagoras Theorem.
In this question we have to find the hypotenuse so we'll have to add.
Let's substitute the values according to the formula.
Now, we can find the value of "x"
- Adjacent= 7 cm
- Opposite= 6 cm
- Hypotenuse= 9.22 cm
We can use any one from SOHCAHTOA.
Here I'm using tan.
Let's substitute the values according to the formula.
We'll have to use tan inverse.
