Is it a Function?

Front

Does this table represent a function?

Back

Yes, a function is defined as a relation where each input has exactly one output.

Front

Which graph does NOT pass the vertical line test?

Back

Graph 1 does not pass the vertical line test, indicating it is not a function.

Front

What is the definition of a function?

Back

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

Front

Is this graph a function or not a function?

Back

Function, as it meets the criteria of having one output for each input.

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 because all x-values are unique.

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

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 example of a function?

Back

An example of a function is f(x) = 2x + 3, where each input x has a unique output.

Front

What is a non-function?

Back

A non-function is a relation where at least one input has multiple outputs.

Front

How can you tell if a relation is a function from a set of ordered pairs?

Back

A relation is a function if no two ordered pairs have the same first element (x-value).
