Identifying Functions

Front

What defines a mathematical function in terms of x and y values?

Back

Each x value must pair with only one y value.

Front

In a function, what is the significance of having each x value pair with a unique y value?

Back

It confirms the function's consistency.

Front

How does a function differ from a non-function in terms of x and y pairing?

Back

A function pairs each x value with exactly one y value.

Front

Why is the table with x values -2 paired with different y values not considered a function?

Back

It allows an x value to pair with more than one y value.

Front

What does the presence of the same x value paired with different y values in a table indicate?

Back

The table represents a non-function.

Front

What can be inferred if each x value in a set of points is paired with only one y value?

Back

The set of points represents a function.

Front

What does the vertical line test determine about a graph?

Back

Whether the graph represents a function.

Front

Which method involves using vertical lines to determine if a graph represents a function?

Back

Vertical line test

Front

If a vertical line intersects a graph at more than one point, what does it indicate?

Back

The graph represents a non-function.

Front

In a mapping diagram, what indicates that it is not a function?

Back

At least one x value maps to more than one y value.
