Is the relation a function?
(1,3) (5,2) (6,0) (-4,7) (1,9)
for x = 1, there are TWO values of y
Therefore NO.
I can't understand what do mean by y has two values
To determine if the relation is a function, we need to check if there are any repeated x-values with different y-values.
In this relation, we have two ordered pairs with an x-value of 1: (1,3) and (1,9). Since they have different y-values, the relation is not a function.
To determine this, you need to analyze the set of ordered pairs given in the relation and see if any x-values have more than one corresponding y-value.
