A set of all allowable input values. If the function graphed, this is the set of all x-values on the graph.

Question

The set of a function output valued (or y-values.)

A rule that tells how one number depends on another. For each input number, there is exactly one output number.

A type of writing that uses a letter to name a function and places parentheses around the independent variable. The notation f(x) is pronounced “f of x”

What words do these describe?

Answer 1

The words you are describing relate to the concepts of functions in mathematics. Here’s a breakdown based on your descriptions:

1. Domain: This refers to the set of all allowable input values (the x-values) for a function.

2. Range: This is the set of all output values (the y-values) for a function.

3. Function: This is a rule that defines how each input (independent variable) corresponds to exactly one output (dependent variable).

4. Function Notation: This is a way of writing that uses a letter (like f) to name a function and uses parentheses to indicate the independent variable (e.g., f(x)), which is pronounced “f of x.”

So, to summarize:

• Domain
• Range
• Function
• Function Notation
