Function, Relations, Domain,and Range

Front

What is the definition of a function?

Back

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

Front

What is the range of a function?

Back

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

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 does it mean for a relation to be a function?

Back

A relation is a function if each input is associated with exactly one output.

Front

Identify the range of the following set of outputs: {3, 0, -1, 0, -2}.

Back

The range is {-2, -1, 0, 3}.

Front

Is the following relation a function? {(1, 2), (1, 3), (2, 4)}

Back

Not a Function (the input 1 has two different outputs).

Front

What is the greatest value in the range for the function y = -2x + 4 when the domain is {-5, -1, 5, 1}?

Back

The greatest value in the range is 14.

Front

What are the x-values in a function called?

Back

The x-values are called the domain.

Front

What are the y-values in a function called?

Back

The y-values are called the range.

Front

If a function has the input x = 2 and the output y = 5, what is the ordered pair?

Back

The ordered pair is (2, 5).
