How should functions be written?

How should functions be written?

You write functions with the function name followed by the dependent variable, such as f(x), g(x) or even h(t) if the function is dependent upon time. You read the function f(x) as “f of x” and h(t) as “h of t”. Functions do not have to be linear. The function g(x) = -x^2 -3x + 5 is a nonlinear function.

How do you write a function definition?

What can a function be used for?

Functions are “self contained” modules of code that accomplish a specific task. Functions usually “take in” data, process it, and “return” a result. Once a function is written, it can be used over and over and over again. Functions can be “called” from the inside of other functions.
