Final answer:
In the notation "t(x) = ...", "t(x)" represents a function of x. The value of t depends on the value of x.
Step-by-step explanation:
In the notation "t(x) = ...", "t(x)" represents a function of x. It means that the value of t depends on the value of x. When we plug in different values for x, we will get different values for t. For example, if we have the function t(x) = 2x, and we plug in x = 3, we get t(3) = 2(3) = 6.
