To select the correct answer, let's break down what "t(x)=..." signifies:
- The notation "t(x)" is a standard way of representing a function, where "t" is the function name and "x" is the variable or input to the function.
- Functions map inputs (in this case, x) to outputs (t(x)). The value of the function output t(x) is determined by evaluating the function t at the specific input x.
Considering these points, the most accurate explanation is:
"The value of t(x) depends on the value of x, since t is a function of x."
Therefore, the correct answer is:
```
The value of t(x) depends on the value of x, since t is a function of x.
```
