Final answer:
The correct algebraic expression for the height of Jacqueline's plant as it grows over time is h = 3n - 7, reflecting the plant's growth pattern of tripling the month number and subtracting 7.
Step-by-step explanation:
The algebraic expression that Jacqueline can use to find the plant's height for any month is given by the relationship, "the plant grows by 7 less than the product of n and 3," where n is the number of months. This can be expressed mathematically as height (h) equals the product of 3 and n, subtracting 7. Therefore, the correct expression is h = 3n - 7.
To further clarify, every month the plant grows by three times the number of that month (3n) and then we subtract 7 from this figure. For example, after 1 month the height increase will be (3 × 1) - 7 = 3 - 7 = -4 (assuming the negative result here is part of a larger growth calculation and the plant initially has a positive height).
