Q. Look at this set of ordered pairs:(1,17)(2,19)(8,1)Is this relation a function?Choices:(A) yes(B) no
Define Function in Ordered Pairs: Define what a function is in terms of ordered pairs.A relation is a function if each input (first component of the ordered pairs) has exactly one output (second component of the ordered pairs). This means that in a set of ordered pairs, no two pairs can have the same first component with different second components.
Examine Given Ordered Pairs: Examine the given set of ordered pairs to see if any input value is repeated with a different output value.The given set of ordered pairs is:(1,17)(2,19)(8,1)We can see that each input value (1,2,8) is unique and does not repeat. Therefore, each input has only one output associated with it.
Determine Relation as Function: Determine if the relation is a function based on the examination in Step 2. Since there are no repeated input values with different output values, the relation given by the set of ordered pairs is a function.
