3.5 Practice - Parts of a Graph

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

What is the vertical line test?

Back

The vertical line test is 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

How can you tell if a graph is a function?

Back

A graph is a function if it passes the vertical line test.

Front

What does it mean for a graph to pass the vertical line test?

Back

It means that any vertical line drawn on the graph intersects it at most once.

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point on a graph, written as (x, y).

Front

What is a graph?

Back

A graph is a visual representation of data or a function, typically plotted on a coordinate plane.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the x-axis and y-axis?

Back

The x-axis is the horizontal line on a graph, and the y-axis is the vertical line.
