Answer:
We conclude that a function is defined as having only one corresponding y-value for each x-value.
Hence, option (C) is true.
Step-by-step explanation:
We know that A function is a certain relationship is defined as having only one corresponding y-value for each x-value.
Considering the function
Here, 
- x is the input and f(x) or y is the output. 
- 'x' is often called an independent value and y is called the 'dependent' value. 
Considering the table
x                      y
1                      2
2                     3
3                     4
4                     5
The values in the table satisfy the function y = x+1.
It is clear from the table that the function has only one corresponding y-value for each x-value. In other words, there is no repetition of 'x' value.
Therefore, we conclude that a function is defined as having only one corresponding y-value for each x-value.
Hence, option (C) is true.

Total students: 5 + 6 + 2 = 13
Total students fluent or a beginner: 5 + 2 = 7
Probability of picking 1 fluent or beginner = total of fluent or beginner over total students:
7/13
