Relations, Functions, linear and nonlinear

Front

What is the range of a relation?

Back

The set of all y-coordinates listed in numerical order.

Front

What is the domain of a relation?

Back

The set of all x-coordinates from a set of ordered pairs, table, or graph.

Front

What are the inputs in a relation?

Back

The x-coordinates in a relation.

Front

What are the outputs in a relation?

Back

The y-coordinates in a relation.

Front

How can the range be represented?

Back

As a set of distinct y-values, e.g., {-2, -1, 0, 3}.

Front

How can the domain be represented?

Back

As a set of distinct x-values, e.g., {1, 2, 5}.

Front

What is a linear function?

Back

A function that graphs to be a straight line.

Front

What is a nonlinear function?

Back

A function that does not graph to be a straight line.

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent a point on a graph.

Front

What is a function?

Back

A relation where each input (x) has exactly one output (y).
