Back

(0, 1)

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What is the range of a function?

Back

The set of all possible output values (y-values) of a function.

Front

What does the graph of a function represent?

Back

The relationship between the input (x) and output (y) values.

Front

What is the y-intercept of a function?

Back

The point where the graph intersects the y-axis (x=0).

Front

How do you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, it is not a function.
