Question

A function must follow a set of established rules, called ____, which specifies how the function must be entered.

Answer 1

A function is a mathematical concept that describes a specific relationship between two sets of numbers. It specifies how each input value is uniquely associated with an output value.

Step-by-step explanation:

A function is a mathematical concept that describes a specific relationship between two sets of numbers, called the input and output. It specifies how each input value is uniquely associated with an output value. A function can be represented using an equation or a rule, which shows how the input values are transformed into output values.

For example, consider the function f(x) = 2x + 1. This function takes any input value x, multiplies it by 2, and then adds 1 to get the corresponding output value.

Rules for entering a function include using appropriate notation, such as using parentheses for input values and properly defining the domain and range of the function.
