Functions or Not Functions Flashcard

Front

Which graph does NOT pass the vertical line test?

Back

Graph 1 does not pass the vertical line test, meaning it is not a function.

Front

Is this graph a function or not a function?

Back

This graph is a function because every input has only one output.

Front

Which ordered pair could you add to the following list of points to create a function? (3, 5) (4, 9) (2, 5)

Back

(1, 9) can be added to create a function.

Front

What is the definition of function?

Back

A function is a relation where every input has only ONE output.

Front

Is this mapping a function or not a function?

Back

This mapping is not a function because at least one input has multiple outputs.

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, written as (x, y).

Front

Can a function have the same output for different inputs?

Back

Yes, a function can have the same output for different inputs, but each input must have only one output.

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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