Is it a function?

Front

What is a function?

Back

A function is a relation where every input has only ONE output.

Front

Which set of values is a function? (9,5) (10,5) (9,-5) (10,-5), (3,4) (4,-3) (7,4) (3, 8), (6,-5) (7, -3) (8, -1) (9, 1), (2, -2) (5, 9) (5, -7) (1, 4)

Back

(6,-5) (7, -3) (8, -1) (9, 1) is a function.

Front

What does the vertical line test determine?

Back

The vertical line test determines if a graph represents a function. If a vertical line crosses the graph more than once, it is not a function.

Front

Which graph does NOT pass the vertical line test?

Back

Graph 1 does NOT pass the vertical line test.

Front

What is an example of a non-function?

Back

Example 2 is not a function because an input maps to multiple outputs.

Front

Does this mapping diagram represent a function? (Yes/No)

Back

Yes, because each input goes to one and only one output.

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

Can a function have the same output for different inputs?

Back

No, a function cannot have the same output for different inputs; each input must map to a unique output.

Front

What is a mapping diagram?

Back

A mapping diagram visually represents the relationship between inputs and outputs of a function.
