Front

Is the graph of a relation a function if any x value is repeated?

Back

Not a Function

Front

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

Back

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

Front

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

Back

R: {-4, -3, 1}

Front

What are all of the y values or outputs in a relation called?

Back

Range

Front

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

Back

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

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

How can you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, it is not a function.
