Domain and Range of a Discrete Graph

Front

What is the definition of 'domain' in a discrete graph?

Back

The domain of a discrete graph is the set of all possible input values (x-values) for which the function is defined.

Front

What is the definition of 'range' in a discrete graph?

Back

The range of a discrete graph is the set of all possible output values (y-values) that the function can produce.

Front

What does the vertical line test determine?

Back

The vertical line test determines whether a graph represents a function. If a vertical line intersects the graph at more than one point, it is not a function.

Front

What is a discrete graph?

Back

A discrete graph consists of distinct, separate points, representing specific values rather than a continuous line.

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the domain?

Back

D: {-4, 0, 1, 2}.

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the range?

Back

R: {-4, -3, 1}.

Front

What is the difference between discrete and continuous graphs?

Back

Discrete graphs consist of isolated points, while continuous graphs are represented by unbroken lines or curves.

Front

How do you find the range from a set of ordered pairs?

Back

To find the range, list all the unique y-values from the ordered pairs.

Front

What is an example of a discrete set of values?

Back

An example of a discrete set of values is {1, 2, 3, 4, 5}.

Front

What is an example of a continuous set of values?

Back

An example of a continuous set of values is all real numbers between 0 and 1.
