Chapter 3: Functions - What is a Function?

A predefined function in algebra is defined as a rule or correspondence between values, called the function’s arguments, and the unique value of the function associated with the arguments.

The function f(x) = 2x + 5 represents a rule or correspondence where the value of the function is equal to two times the input plus five.

The pow(x, y) function calculates the value of x raised to the power of y.
