Question

Change a Relation to Make It a FunctionThe relation R is shown below as a list of orderedpairs.R= {(1, 4), (1, 3), (-1, 3), (2, 15) }Which ordered pairs prevent this relation frombeing a function?(1, 4) and (1, 3), because they have thesame x-valueO (1, 3) and (-1, 3), because they have thesame y-valueDONE

Answer 1

For a function, an input or value of x must not have more than one output or value of y. Considering the given relation,

R= {(1, 4), (1, 3), (-1, 3), (2, 15) }

The input value of x = 1 corresponds to two output values of y = 3 and y = 4

Thus, the ordered pairs that prevent this relation from being a function is

(1, 4) and (1, 3), because they have the same x-value
