Front

What is the set of y values or outputs for a relation called?

Back

Range

Front

What is the set of x values or inputs for a relation called?

Back

Domain

Front

What determines if a relation is a function?

Back

A relation is a function if each x-value has only one y-value paired with it.

Front

What does the inequality 0 < x + 7 < 9 represent?

Back

-7 < x < 2

Front

Does the graph represent a function if any x-value has more than one y-value?

Back

No, it does not represent a function.

Front

Define 'domain' in the context of relations.

Back

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

Front

Define 'range' in the context of relations.

Back

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

Front

What is a relation in mathematics?

Back

A relation is a set of ordered pairs, typically representing a relationship between two sets of values.

Front

What is the vertical line test?

Back

A method 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

If a relation has the pairs (1,2), (1,3), (2,4), is it a function?

Back

No, because the x-value 1 has two different y-values (2 and 3).
