Question

The relation Ris shown below as a list of ordered

pairs.
R = {(1,4), (1,3), (-1,3), (2, 15) }
Which ordered pairs prevent this relation from
being a function?
(1,4) and (1,3), because they have the same
X-value
(1,3) and (-1,3), because they have the
same y-value
DONE

Answer 1

(1,4) (1,3) have the same x value!

Answer 2

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

Step-by-step explanation:

A function is a set of ordered pairs which is related by an equation. A function cannot have a set of ordered pair with the same x coordinate, but it can have ordered pairs with repeated y values that is each x coordinate is unique and different.

The set of ordered pair (1,4) and (1,3) have the same X coordinate of 1, therefore it cannot be a function but (1,3) and (-1,3) can be represented as a function.
