In the relation {(-1,2), (-2,4), (2,5), (0,-2), (2,0)}, what domain value corresponds to the range value -2?

Back

0

Front

Which of the following relations 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

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

What is the definition of a function?

Back

A function is a relation where each input (x value) has exactly one output (y value).

Front

What is the definition of a relation?

Back

A relation is a set of ordered pairs, where each pair consists of an input and an output.

Front

If a relation has the ordered pairs {(2,3), (2,4), (3,5)}, is it a function?

Back

No, because the input 2 has two different outputs (3 and 4).

Front

What is the range of the relation {(1,2), (2,3), (3,4)}?

Back

{2, 3, 4}.

Front

What is the domain of the relation {(4,5), (5,6), (6,7)}?

Back

{4, 5, 6}.
