Functions Vocabulary

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols, typically written as f(x), where f represents the function and x is the input variable.

Front

What does it mean for a graph to be a function?

Back

A graph is a function if every x-value (input) has exactly one corresponding y-value (output). This means that no vertical line can intersect the graph at more than one point.

Front

What does it mean for a mapping to be a function?

Back

A mapping is a function if each input is paired with exactly one output. This means that no input can have multiple outputs.

Front

What are the x values in a function called?

Back

The x values in a function are called inputs.

Front

What are the y values in a function called?

Back

The y values in a function are called outputs.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is an ordered pair in the context of functions?

Back

An ordered pair is a pair of numbers (x, y) that represents a point on a graph, where x is the input and y is the output.

Front

What is a vertical line test?

Back

The vertical line test is a method used to determine if a graph represents a function. If a vertical line intersects the graph at more than one point, it is not a function.

Front

What is a function table?

Back

A function table is a table that lists input values and their corresponding output values, showing how the function operates.
