The first thing we must do for this case is to observe the value of the y coordinate for a given value of the x coordinate. We have then: f (x) = - 4: occurs when x = 0 On the other hand, for x = 2 we have: f (2) = - 2 Answer: f (x) = - 4: occurs when x = 0 f (2) = - 2
If you do 35 times 4 you get 140. Divide 140 by 20 and you get 7 . Therefore the manager would have to buy 7 packs of candy bars and 4 packs of water bottles
