ALG. 1 - Q2: WEEK #6 FLASHCARD

Front

What is the domain of a relation?

Back

The domain of a relation is the set of all possible x-values (input values) that can be used in the relation.

Front

How do you find the domain of a relation given a set of x-values?

Back

To find the domain, identify the smallest and largest x-values in the set and express it as an interval.

Front

What is the range of a relation?

Back

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

Front

How do you determine the range of a relation given a set of ordered pairs?

Back

To determine the range, extract all the unique y-values from the ordered pairs.

Front

What does it mean for a graph to be discrete?

Back

A discrete graph consists of distinct, separate points and does not connect between points.

Front

What does it mean for a graph to be continuous?

Back

A continuous graph has no breaks or gaps; it is a smooth line or curve.

Front

What is an ordered pair in a relation?

Back

An ordered pair is a pair of numbers (x, y) that represents a point on a graph, where x is the input and y is the output.

Front

How can you represent the domain of a relation using interval notation?

Back

The domain can be represented in interval notation by using brackets for inclusive endpoints and parentheses for exclusive endpoints.

Front

What is the significance of identifying the domain and range in a relation?

Back

Identifying the domain and range helps understand the limitations and behavior of the relation.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) is associated with exactly one output (y-value).
