Which represents a function ?

Second option

Step-by-step explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.

For the first table, this would not represent a function.

Notice that the -3 and the -3 correspond to different y-coordinates. In order for a relation to be a function, each x-coordinate must pair with one y-coordinate.

The second relation would be a function because notice that each x-term appears only once with a unique y-term so your answer would be the second one.

For the third table, the 0 gets paired up with two different y-values.

For the last relation, the x-term, -12, gets paired up with 4 and 24 which means that the relation can't be a function.

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

351°f
