Short Answer

Expert verified

The set of ordered pairs is not a function.

Step by step solution

01

Step 1. Given information

The given set of ordered pairs is(−3,−5),(−2,−4),(−1,−3),(0,−2),(−1,−1),(−2,0),(−3,1)

02

Step 2. Determine if it represents a function or not.

A set of ordered pairs is said to be function, if for each input or xvalue there is exactly one yvalue or output.

From the ordered pairs (-2,-4)and (-2,0), it is very clear that the xvalue is matched with two yvalues.

Therefore, the set of ordered pairs is not a function.
