Home work help I would like if someone would break these problems down for me thanks

Pre-calculus Unit 1A - Modeling Name 1) Grettell has currently submitted 15 assignments. For the next 8 days she submits one assignment in each of her 3 classes each day. Analytically and graphically describe the relation between the number of submitted assignments as a function of the day number. Label and put a scale on the axes. Analytical Function Definition (equation): Is this function discrete, continuous, or discontinuous? How do you know? Domain: Range: 2) You are doing a chemistry experiment by adding baking soda to vinegar. You start with 8 cubic inches of vinegar. When you add the baking soda, the volume of the solution in volume by 60 cubic inches every second for 6 seconds. Analytically and graphically describe the relation between the volume of the solution as a function of the time since you added the baking soda. Label and put a scale on the axes.
