Back

Function

Front

Which relation is NOT a function? {(1,-5), (3,1), (-5,4), (4,-2)}, {(2,7), (3,7), (4,7), (5,8)}, {(1,-5), (-1,6), (1,5), (6,-3)}, {(3,-2), (5,-6), (7,7), (8,8)}

Back

{(1,-5), (-1,6), (1,5), (6,-3)}

Front

A relation where every input yields one and only one output is called what?

Back

Function

Front

What is the Vertical Line Test used for?

Back

To determine if a relation is a function.

Front

If a relation has the ordered pairs {(2,3), (2,4)}, is it a function?

Back

No, because the input 2 has two different outputs.

Front

What is a function?

Back

A relation where each input is associated with exactly one output.

Front

Can a function have the same output for different inputs?

Back

Yes, a function can have the same output for different inputs.

Front

What is an example of a function?

Back

f(x) = x^2, where each input x has one output.
