Back

Range

Front

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

Back

D:{0, 1, 2, -4} R:{1, -3, -4}

Front

Is the relation a function? Why? (x-value 11 has two y-values)

Back

No, because the x-value 11 has two y-values pair with it.

Front

What is a function?

Back

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

Front

What is the range of a function?

Back

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

Front

What is the domain of a function?

Back

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

Front

Can a function have the same y-value for different x-values?

Back

Yes, a function can have the same y-value for different x-values.
