It's a function because every x-value that you plug in will have a single y-value associated with it.
DOMAIN (x-values): All Real Numbers
(since any x-value that you plug in will work)
RANGE (y-values): y>=8
(y will never be less than 8 because the y-intercept is 8 and the graph goes up from there)
