Find the domain and range of the relation, and state whether or not the relation is a function.
{(1, 3), (2, 3), (3, 3), (4, 3)}

A relation is simply a set of ordered pairs, while a function is a set of ordered pairs in which each x-coordinate has only ONE y-coordinate associated with it.

The first elements in the ordered pairs (the x-values), form the domain.  The second elements in the ordered pairs (the y-values), form the range.  

In the set,

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
