Linear Graph Characteristics Review

Front

What is the range of a set of ordered pairs?

Back

The range is the set of all second elements (y-values) from the ordered pairs.

Front

What is the domain of a function?

Back

The domain is the set of all first elements (x-values) for which the function is defined.

Front

How do you determine the interval where a function is constant?

Back

A function is constant over an interval if it does not change in value for all x in that interval.

Front

What does end behavior of a graph refer to?

Back

End behavior describes how the values of a function behave as x approaches positive or negative infinity.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, written as (x, y).

Front

How do you find the range from a set of points?

Back

List all the y-values from the points and remove duplicates to find the range.

Front

What does it mean for a function to be defined for all real numbers?

Back

It means that the function has a valid output for every possible input value of x.

Front

What is the significance of the x-axis in a graph?

Back

The x-axis represents the input values (domain) of a function.

Front

What is the significance of the y-axis in a graph?

Back

The y-axis represents the output values (range) of a function.

Front

How can you identify a constant function on a graph?

Back

A constant function appears as a horizontal line on a graph.
