Domain and Range Functions Practice

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

How can you determine if a graph represents a function?

Back

A graph represents a function if any vertical line drawn through the graph intersects it at most once (Vertical Line Test).

Front

What is the difference between a function and a relation?

Back

A relation is any set of ordered pairs, while a function is a specific type of relation where each input has one output.

Front

Identify if the following is a function: {(1,2), (2,3), (1,4)}

Back

Not a Function (the input 1 has two different outputs: 2 and 4).

Front

Identify if the following is a function: {(1,2), (2,3), (3,4)}

Back

Function (each input has a unique output).

Front

What is the domain of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

D: {0, 1, 2, -4}.

Front

What is the range of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

R: {1, -3, -4}.

Front

Which of the following sets is a function? {(1,2), (2,3), (3,4)}, {(1,2), (1,3), (2,4)}

Back

{(1,2), (2,3), (3,4)} (the first set is a function).
