domain=range of x
codomain=range of y=the range of values of f(x)

Okay! I was think 3-12 because the graph goes from three, and then up 12.

the values that the graph(or y) can take is called the 'range' of graph or function.
sence, 3 to 12 is range of y.

A relation is
the output (y) values of the relation
the input (x) values of the relation
a set of points that pair input values with output values <--- This, correct
x and y values written in the form (x, y)

yes, a RELATION is simply the set of ordered pairs (x,y)
so that is correct.
