Title
Is a Function
Is not a Function
{(2, 2),(4, 4),(6, 6),(8, 8)}


{(0, 3),(3, 5),(5, 6),(8, 4)}


{(1, 2),(3, 3),(4, 8),(6, 3)}


{(3, 4),(5, 2),(5, 6),(7, 3)}

Answer 1

The first one is a functions because in a relation (a,b) a is the domain and b is the range of the relation

So in the first one we get different values of b for different values of a, so it'll be a function.

A function can have different values of b for different ' a ' however a function cannot different values of a for the same b

So, second will also be a function

EVEN THIRD will be a function

And even the fourth one is a function
