Relations and Functions

Front

All of the x-coordinates or inputs are called what?

Back

Domain

Front

What is the best definition of function?

Back

Every input has exactly one output

Front

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the domain and range?

Back

Domain: {-4, 0, 1, 2}; Range: {-4, -3, 1}

Front

What is the domain of the table? Options: {-4, 0, 1, 3}, {-2, 0, 2, 3}, {-4, -2, 0, 1, 2, 3}, { (0, 0), (2, -4), (3, 3), (-2, 1) }

Back

{-2, 0, 2, 3}

Front

What is the range of the following graph?

Back

{-5, -1, 0 , 1, 5}

Front

What is the domain and range?

Back

Domain: {-3, -1, 2, 4}, Range: {0, 4, 7}

Front

Which relation has a domain of {3,7} and a range of {0,5} ? Options: {(3,5), (3,7), (0,5), (0,3)}, {(3,0), (7,0), (3,5), (7,5)}, {(3,0), (3,5), (3,7), (7,5)}, {(7,0), (5,7), (3,5), (7,5)}

Back

{(3,0), (7,0), (3,5), (7,5)}

Front

Does this table represent a function or not a function?

Back

Function

Front

Is the relation a function? Why?

Back

Yes, because each x-value has only one y-value paired with it.

Front

Is this mapping a function or not a function? Why?

Back

No, because the x-value 6 has two y-values paired with it.
