Domain and Range Bootcamp

Front

Is the relation shown a function?

Back

No, because the x-value 11 is paired with 5 and 8.

Front

Which of the following best describes a function?

Back

A special relationship where each x value has only one y value.

Front

What is the domain of a relation?

Back

The set of all x-values.

Front

What is the range of the mapping?

Back

{1, 2, 4}

Front

What is the domain of the relation shown in the table?

Back

{6, 18}

Front

Define 'function' in mathematical terms.

Back

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

Front

What is the range of a function?

Back

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

Front

How can you determine if a relation is a function using a graph?

Back

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

Front

What is an example of a function?

Back

f(x) = 2x + 3 is a function because each x-value has one corresponding y-value.

Front

What is an example of a relation that is not a function?

Back

The relation {(1, 2), (1, 3)} is not a function because the x-value 1 is paired with two different y-values.
