A function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has precisely one output and the output can be linked to its input.
A relationship between a collection of inputs and outputs is known as a function. A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output.
Each function has a range, co-domain, and domain.
The given function is k(t).
k(t) = t-4
Here, the value of k(t), depends upon the value of 't'.
k(t) is the dependent variable whereas 't' is the independent variable.
