Which two sets of ordered pairs represent a function ?

Second option.

Fifth option.

Step-by-step explanation:

By definition, a relation is a function only if each input value (each x-value) has one and only one output value (y-value).

Knowing this, we can check each set of ordered pairs given in the picture:

First option: Notice that the input value has two output values ( and ), and the input value has two output values ( and ); therefore this set of ordered pairs does not represent a function.

Second option: Observe that each input value has one output value; therefore this set of ordered pairs represents a function.

Third option: Notice that the input value has two output values ( and ), and the input value also has two output values ( and ). Therefore this set of ordered pairs does not represent a function.

Fourth option: Since  all the ouput values belong to the input value , we can conclude that this set of ordered pairs does not represent a function.

Fifth option: Observe that each input value has one output value; therefore this set of ordered pairs represents a function.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
