  Read the scenario. Levi examines the effect of fertilizer on the growth of tomato plants. Over a 15-day period, he gives the plants fertilizer on Days 1, 4, 7, 10, and 13. He measures and records the height of all of his plants on Days 3, 6, 9, 12, and 15. His observations are shown in the table below. A data table showing four plants, the amount of fertilizer each is given (in milliliters), and their heights (in centimeters) at 6 separate measuring periods (in days): Plant A: 0 milliliters of fertilizer. Heights: (day 0, 4 centimeters) (day 3, 7), (day 6, 10), (day 9, 12), (day 12, 15), (15, 18). Plant B: 10 milliliters of fertilizer. Height: (day 0, 4 centimeters), (day 3, 9), (day 6, 14), (day 9, 19), (day 12, 21), (day 15, 25). Plant C: 20 milliliters of fertilizer. Height: (day 0, 4 centimeters), (day 3, 12), (day 6, 20), (day 9, 27), (day 12, 34), (day 15, 42). Plant D: 30 milliliters of fertilizer. Height: (day 0, 4 centimeters), (day 3, 13), (day 6, 22), (day 9, 29), (day 12, 38), (day 15, 46).
