What is the vertical line test?

Back

A method to determine if a graph represents a function. If any vertical line intersects the graph at more than one point, it is not a function.

Front

What defines a function in mathematics?

Back

A relation where each input (x-value) has exactly one output (y-value).

Front

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

Back

It means that for every x-value, there is only one corresponding y-value.

Front

Can a function have the same output for different inputs?

Back

Yes, a function can have the same output for different inputs, as long as each input has only one output.

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represents a point on a graph.

Front

Do the ordered pairs (1, 2), (3, 4), (5, 6), (7, 8) represent a function?

Back

Yes, because each x-value is unique.

Front

What is a mapping in the context of functions?

Back

A representation of how each input is paired with an output.

Front

What is the difference between a function and a non-function?

Back

A function has one output for each input, while a non-function may have multiple outputs for a single input.

Front

What is a domain in a function?

Back

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

Front

What is a range in a function?

Back

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