Use the set of ordered pairs to determine whether the relation is a function. Then find the domain of the relation, and the range of the relation. {(-5, 6), (-2, -4), (-1, 5), (-1, -5), (8, 3)} Is the relation a function? (enter yes or no) The domain of the relation is {}. (Enter the domain elements in numerical order (least to greatest) and separated by commas without spaces.) The range of the relation is {}. (Enter the range elements in numerical order (least to greatest) and separated by commas without spaces.)

A blogger earns R ( x ) = 4 x + 0 . 021 x 2 in revenue, where x is the number of subscribers and has a cost of C ( x ) = 2250 + 6 x . Let P ( x ) be the profit when there are x subscribers. Write a function giving the blogger’s profit when there are x subscribers. P(x) = The blogger needs at least subscribers to break even.
